0.6.0

This version feels pretty stable.
I can use it over ranger most of the time now.

Some notable changes are:

fix crash when resizing terminal
printing the extension of file if name is too long
fix crash when toggling hidden files
renaming files now work
- can set cursor the start/end of file name or start from scratch
fix crash with newline characters in filename
support for wide character editing
support for custom keymapping is added back
support for selection is added back
paste no longer stops main thread
fix deleting symlinks recursively
moving files across filesystems now work
moving files no longer does unnecessary copies (when on the same filesystem)
remove dependency on fs::DirEntry as this caused large amounts of unnecessary open directories, preventing unmounting of filesystems
fix u32 type cast when it should have been ncurses::chtype type cast depending on the system configuration of ncurses

searching for files
theming support
better logic for displaying directory listings
- particularly not forcing the cursor to be between index 0-offset
add support for parsing ~/ and expanding inside keymap.conf for changing directories
clean ups
