2001-09-15    <NotZed@Ximian.com>

        * mail-vfolder.c: Major rewrite of most of the guts, handle
        changes based on signals and events, etc.  Use the main storage
        handling code that imap uses, etc.

        * mail-tools.c (mail_tool_uri_to_folder): Dont special case
        vfolder: anymore.

        * component-factory.c (owner_set_cb): use vfolder_load_storage(),
        new function to setup vfolder storage, after interaction has been
        enabled only.  This might need some tweaking ...
        (storage_remove_folder): Removed all the folder lookup stuff.
        Just delete the folder based on the path passed in.  There should
        be no reason this wouldn't work, right?

2001-09-14    <NotZed@Ximian.com>

        * mail-ops.c (get_folderinfo_get): Only add vtrash folder info, if
        store supports vtrash.

        * component-factory.c (mail_load_storage_by_uri): Let 'vfolder'
        stores show up too.

2001-09-13    <NotZed@Ximian.com>

        * mail-vfolder.c (vfolder_uri_to_folder): Open a vfolder then set
        its expression, since name?query open method is removed.
