[Filesystem] Some filesystem adapter work with IDs instead of paths

[Elfangor93]

Some filesystems like Filesystem - DPMedia Google can not handle folder paths and filenames because the underlying api works with IDs instead of paths.

So this file path
/images/test_folder/example.jpg

is represented by the Google Drive API as
/1HZBOg4zvXHCN2JxlBWlzFzhDoK14wO41/1tAkJxsKd8ZEv59lg-nEVrYs1YbOZC_XE/1VQTPW51Y4qob7rRgvM9uTLNGZ8HQFaEJ.jpg

If we want to support this kind of filesystems, we need to map folder paths and file names to IDs. this would make further database columns in #__joomgallery and #__joomgallery_categories necessary.

path	ID
images	1HZBOg4zvXHCN2JxlBWlzFzhDoK14wO41
test_folder	1tAkJxsKd8ZEv59lg-nEVrYs1YbOZC_XE
example.jpg	1VQTPW51Y4qob7rRgvM9uTLNGZ8HQFaEJ.jpg
