when the SKIP_DELETED flag was set, no recent changes where returned for
media only queries, becuase file checks where done on page files instead
of media files

The previous regexp approach failed for empty headers.

passwords now need to be reset within 3 days of requesting the password
change mail

Changing passwords might not be available.

This removes the cachekey parameter again and instead follows
@michitux's suggestion to trigger an event for the cache usage

Improbement and "bug"fixing of the xmlrpc interface

use in_array to filter groups instead of preg_grep for acl

tss..

Some plugins want to dynamically switch the template based on users,
namspaces or the phase of the moon. Having fixed paths in a unchangable
constant prevents this.

This changes deprecates the DOKU_TPL* constants in favor of two new
tpl_* functions that return the correct paths based on the $conf
variables which can be changed from the DOKUWIKI_STARTED event.

The function tpl_getFavicon() was doing more than its name was implying. Therefore the new tpl_getMediaFile() was introduced (which is doing nearly exactly the same) and tpl_getFavicon() was deprecated.
tpl_favicon() can still be used, though.

Templates authors should support these to make the transition between templates easier. Templates which already have a sidebar could first check for $conf['sidebar'] and use it if it's defined, otherwise use their old own sidebar functionality to stay backwards-compatible.

This is in preparation for the new default template. This also updates the tpl_actiondropdown() to use most of them.
