Subject: [PATCH] i3-dmenu-desktop: List filenames of .desktop files

In addition to 'name' and 'command', add a third entry type 'filename'
to list the filenames of the .desktop files (e.g., 'firefox.desktop'
would be display as 'firefox').

Command line option '--entry-type' can be specified multiple times.

fixes #930
