source: trunk/src/org/expeditee/auth/AuthenticatorBrowser.java@ 1440

Last change on this file since 1440 was 1440, checked in by bnemhaus, 5 years ago

Reordered the default FrameDirs, ImageDirs and AudioDirs to what I think is a logical order.
Also renamed the CURRENT.USER flag to CURRENT_USER to be inline with other flags like CURRENT_FRAMESET
