Add config option to change default listing view flags.

Version 0.4.2.

Add 't' to navigate to link target.

Add 'o' to open file with $ROVER_OPEN.

Version 0.4.1.

Make use of shell optional.

Launch external programs through shell. Passing $PAGER directly as argv[0] of a subprocess only works when $PAGER is simply the name of a binary file, such as "less". Users may want to hardcode command-line options, e.g. PAGER="less -N", so we need to do something like argv = {"sh", "-c", $PAGER}. The same applies to $SHELL and $EDITOR.

Version 0.4.0.

Add executable file color customization.

Support color customization of other kinds of files.

Add missing description to config option.

Add optional alert to inform that a batch operation has finished.

Swap default keybindings for refresh and rename. This is more consistent to the general idea of making file operations harder to do accidentally.

Change default keybinding x->D to avoid confusion.

Version 0.3.0.
