- improved performance with not using regexps when not necessary
- added support for element hiding even with domain restrictions
- almost all types of rules are supported now
* exceptions are only some special cases when rule has
unssuported options (part of rule after $ character)
* those rules are ignored
- much faster history loading (loading history entries only when
needed - eg. expanding top level items)
- less memory usage (sidebar and manager are using the same model)
- searching is now performed on title and url
- clear private data -> clear history is now working properly
