This is preliminary changes in order to track preview threads and progress.
The current setup is we just kick off a new thread to load
the given directory whenever we see the directory content
does not exist in history.
We don't track these threads or which tab these requests
came from. When the result is returned, we just assign it
to the current tab, instead of the tab that actually
initiated the request.
By adding uuid, we can now track which tab requested the
preview and assign it accordingly.
This will also allow us to track the status of the preview,
so we can display to the user a loading state,
when a directory is taking longer than usual to load.
This will also solve the problem of kicking off multiple
threads to read the same directory for the same tab.
Now these threads can be stored and tracked.
- side: fix reload not honouring tab sort options
- use tab specific options whenever we need to reload stuff

* Add "Visual-Mode"
This adds a "visual-mode" file selection feature where a range-selection follows the file-cursor.
Description of usage is added to the docs.
Also, the "normal" and the new "visual-mode-selection" are now preserved
when a `DirList` is reloaded.
Wrap-up of changes:
* Add command `toggle_visual`, mapped to `V`
* Add command `escape`, mapped to `ESCAPE`
* Add style `[visual_mode_selection]` for file entries which are
"temporarily" selected by visual-mode
* For `JoshutoDirEntry`, the attribute `selected` has been renamed to
`permanent_selected`, and a second selection-attribute
`visual_mode_selected` has been added. "Setters" and "getters" have
been adapted/added accordingly. The former "getter" for the `selecetd`
attribute still exists and returns `True` for an entry which is
"permanant selected" _or_ "visual-mode selected". So any higher logic
which acts on selected files does not need to care about "how" and
entry is selected.
* Each `JoshutoDirList` has an optional index of the file where
visual-mode has been entered and re-calculates the "visual-mode
selecetd" status for each entry any time the cursor-index changes.
* The footer has been extended so it shows a "VIS" marker when the user
is in visual-mode.
This implementation of visual-mode is a bit different from the ranger
one, where the visual-selection is turned into a "normal selection" when
a command (like `copy-files`) is issued. This implementation keeps
both selections separate until the user toggles back to "normal mode".
Only then the visual-selection is taken over to the "normal selection".
The user also can withdraw the visual-selection with `escape`.
The `escape` command may be used also for other "reset"-actions in the
future.
* fix syntax for Rust stable
* cargo clippy

--output-file is used for all output by joshuto
and can be specified what to output by:
`quit --output-current-directory`
`quit --output-selected-files`

The preview-removed-hook was called in each main loop cycle if no
preview area was shown and a removed-hook was configured.
|
|
When the size of the preview area changes, the "preview shown hook" is
called to give a chance to update the size and/or position of the
preview image.
|
|
* Calling preview removed hook when help page shown
* Better function names and documentation
* syntax fix
|
|
* Continuous scrolling
The scrolling behavior is changed from “paging” to a continuous
scrolling. Joshuto keeps a buffer from the cursor to each end of the
list, which is configured by `[display] scroll_offset`. If the terminal
height is too small to keep the distance, the buffer is set to a value
that assures that the cursor is at least as close to the end the user is
scrolling towards as to the other end of the visible list.
If the window is resized and the cursor jumps out of scope, the viewport
is adjusted when changing the index next time.
Possible improvements:
* Issue a viewport update on terminal geometry change
* When scrolling down to the bottom, don't allow an empty section
beneath the last entry
* Update documentation for scroll_offset
* remove unused variable
* keep viewport index when replacing dirlist
* Don't keep copy of scroll_offset in JoshutoDirList
* sanity: remove obsolete parameter

* Update view on filesystem changes
AppContext owns an INotifyWatcher, which watches the visible directories
(max. three). The list of directories to watch is updated on every
event. If a filesystem change is announced, a "soft-update" of the
current view is issued.
* Specific "watchers" for Linux and MacOS
For supervision of filesystem changes, specific `notify::Watcher`
implementations are used for Linux and MacOS.
Builds will likely fail for other OSes as
`notify::recommended_watcher` may return some specific watcher
implementation but the code just expects a `NullWatcher`.
* remove dead code
