Subject: [PATCH] include_once support for javascript
The include syntax was changed and enhanced by a include_once statement.
Syntax:
/* DOKUWIKI:include somefile.js */
/* DOKUWIKI:include_once someotherfile.js */
Note: include_once uses the basename of the inlcuded file to determine if
it was previously loaded. You need to use something unique for it to
make sure it is correctly loaded.
Note: included files are not checked for updates by the cache logic. You
need to touch the master file for updating the cache
Note: includes are *not* supported inside included files to avoid any
circular references
