             it's quicker to search numbers that are out of outer, than strings

               an 'All bitmaps' item is alway first, and 'All files' is always last

  folders comes without trailing slash

  %miranda_profile%     -> same as MS_DB_GETPROFILEPATH, base folder for all profiles
  %miranda_userdata%    -> the active profile folder (home of the .dat file and all
                           profile data)
  %miranda_path%        -> home path of the miranda installation (installation path
                           of miranda32/64.exe
  %miranda_profilename% -> Name of the profile in use. Essentially, the name of the
                           .dat file without file name extension. Also: the folder name
                           relative to %miranda_profile% where all profile data is stored.
  %miranda_logpath%     -> base folder for log files. This is \Logs relative to the
                           current profile folder.
  %miranda_avatarcache% -> base folder for all protocol avatars. internal use only.

  the following variables operate on contacts. REPLACEVARSDATA::hContact must be
  supplied by the caller.

  %nick%                -> a contact nick name.
  %proto%               -> internal protocol name for a given contact. NOT the user-
                           defined account name.
  %userid%              -> Unique ID for a given contact (UIN, JID etc.)

  the following variables are system variables - unrelated to miranda profiles.

  %appdata%             -> same as %APPDATA% environment variable.
  %destkop%             -> location of the desktop folder in a user's profile.
  %mydocuments%         -> location of the "My Documents" shell folder.
