Proper phpdoc for Horde_Autoloader

Cleanup some code to Horde coding standards
[mms] Add Horde_Autoloader_ClassPathMapper_PrefixString mapper implementation.
[mms] Saving cache data should be handled in a shutdown function, not a destructor.
[mms] Remove duplicate paths when initializing the default Autoloader.
Use PrefixString autoloader for application paths.

More efficient than calling preg_match().

Also, don't add duplicate path mapper entries to autoloader in
Horde_Registry.
No need to go through __get() to access these variables
More efficient Horde_Stream#search()

About 3x as fast, according to xdebug.
Optimizations for email parsing

2x increase in performance per xdebug
Correctly resize message area when adding addresses
preset HTML IFRAME to height auto so that window does not jump when image content is loading
[mms] Fix sieve driver correctly identifying mailing list when determining whether to send vacation messages (Bug #12938; skhorde@smail.inf.fg-bonn-rhein-sieg.de).
