Add filetype configuration menu entries

This adds a "Filetype Configuration" under Tools->Configuration Files
with all filetype configuration files (grouped by language type).

This patch mostly reuses the stuff we already have in Geany - the menu
creation code from Document->Set Filetype, file creation in the .config
directory if it doesn't exist (similarly to filetypes.common) and config
file reloading when the file gets updated.
