change the behavior of open and alt-open on standard files

The logic behind opening has changed to allow easier opening of files in non terminal applications without closing broot.

**Old behavior:**
- in case of enter or double-click
   - on a directory: open that directory, staying in broot
   - on a file: open the file, quitting broot
- in case of alt-enter
   - on a directory: cd to that directory, quitting broot
   - on a file: cd to that file's parent directory, quitting broot

**New behavior:**
- in case of enter or double-click
   - on a directory: open that directory, staying in broot
   - on a file: open that file in default editor, not closing broot
- in case of alt-enter
   - on a directory: cd to that directory, quitting broot
   - on a file: open that file in default editor, quitting broot
