Two features: page menu and custom filters

Add all reports dynamically into the page menu. The layout xml will unset the original page menu block and adds the clean page menu block. If you find any other possibility for injecting dynamic menu items let me know asap :-) You have to clear the cache if you change the title or add/remove a new report.

Second feature adds the possibility for custom filters for columns in the Report/View/Grid.php file.

Auto reformatting also removed some superfluous whitespaces / tabs ;-)
@SchumacherFM let's put a limit in here.  I think I have like 15 reports already and growing.  I was wondering whether it would make sense to do a sort order or something to allow people to pick the hightest priority reports that they want to add to the menu.  But maybe we do that down the line.
