Patch is mostly created by script in egroupware/doc/fix_depricated.php in separate commit.
I do NOT advice to apply this patch to a production system (it's commited to trunk!), as the automatic modified regular expressions have a good change to break something ...
2) added the possebility to select multiple tpls from the search-list to delete them
3) added the developer_tools solangfile class to etemplate to be able to write lang-files, even if the developer-tools are not installed
