Add simple vim mode
This commit adds a "vim_mode" setting (false/`0` by default) that causes
keys to be remapped in the following way by the `ScreenManager`:
+ h -> LEFT
+ j -> DOWN
+ k -> UP
+ l -> RIGHT
+ LEFT -> h (toggle help)
+ DOWN -> j (noop)
+ UP -> k (open kill menu)
+ RIGHT -> l (lsof current process)
+ K (Shift+K) -> k (open kill menu)
+ J (Shift+J) -> K (toggle show/hide kernel threads)
+ L (Shift+L) -> l (lsof current process)
I couldn't figure out where the manpage documentation is in the repo,
though I admittedly did not look particularly hard.
I believe this change would be a welcome option for heavy vim users like myself
who would like a familiar way to get around in htop.
