- Patch by JonBob: for consistency and readability, add brief descriptions of each source file inside the @file comment block at the head of the file. This helps with Doxygen indexing, and also allows neophytes to see what a file does immediately on opening the source, regardless of the organization of the hooks.

- New locale module thanks to Gerhard, Goba, Marco, Kristjan and others.

  The new locale module provides every functionality on the web interface, so you don't need to edit the configuration files or add columns, when you add a new language. This module is an integration of the old locale and localegettext modules, plus a bunch of logic to parse Gettext Portable Object files (opposed to Machine Object files, as supported by localegettext).

  Note: I made some minor changes to the context-sensitive help texts and to some of the status messages.
