/* ******* FILEBROWSER DESIGN ********
there is only one treestore left for all bluefish windows. This treestore has all files
and all directories used in all bluefish windows. This treestore has a column for the pixmap
and the name (both shown to the user), but also the GFile for the full path (excluding the
trailing slash for directories, see #1), and the type. This treestore is in main_v->fb2config. Each file
or directory added to the treestore is also added to a hashtable in main_v->fb2config

the GUI uses two filtermodels on top of the treestore, and then two sortmodels, so they can
show a specific part of the treestore (for example with a basedir other then the root, or with
some filter applied).

#1) the hash for file:///home/ is different from file:///home so we should choose which hash is
to be stored in the hashtable. The method gnome_vfs_uri_get_parent() returns directories without
the trailing slash. So it is convenient to use directories without trailing slashes all the way.

alex: g_hash_table_new(gnome_vfs_uri_hash, gnome_vfs_uri_hequal) is what you're supposed to do
