LibGUI: Add allowed file extensions to FileSystemModel

Browse Source 
This allows FileSystemModel to take an optional list of allowed file
extensions which it will use to filter out all files that don't end
with that file extension.

The file extensions are set via `set_allowed_file_extensions` which has
a coresponding `get_allowed_file_extensions`.
