Add .gitignore to ignore compilation products

If a filename has Unicode chars, the alignment is broken. Hence moving name to
the last column. This also makes the view compact.
Moving block and char dev indicators in the space for size.

Invoking nnn with:

nnn dir
nnn ./dir
nnn dir

wouldn't allow user to navigate to parent directory.

Add keybind 'Ctrl-k' to copy the absolute path of the file under the cursor if environment variable NOICE_COPIER is set.

1. Highlight the currently selected item in reverse video.
2. Fix: remember the current item when toggling detail view.

noice truncates the cwd string dynamically. If the numbers of columns is lesser than the length of the path, cwd is truncated so that the correct path cannot be resolved. We should try to resolve the full path instead.

B - Block Device
C - Character Device
D - Directory
E - Executable
F - Fifo
L - Symbolic Link
R - Regular File
S - Socket

1. The detailed view shows file type and size using keybind 'd'. Disabled by default.
2. Option 's' sorts dir entries by descending order of size.

The contents of the directory may be changed from the shell by adding or deleting content. Permissions may have changed too. We must re-populate the contents of the current directory.

Once set, the default filter is updated.  This means that
toggle dot will also work as expected when noice is executed
as root.
