[svn] * Avoid access to bag item prototype for getting bag size, use related item update field instead as more fast source.

* Better check client inventory pos data received in some client packets to skip invalid cases.
* Removed some unnecessary database queries.
* Make guid lookup for adding ignore async.
* Added two parameter versions of the AsyncQuery function
* Make queries for adding friends async. - Hunuza
* Replace some PQuery() calls with more simple Query() - Hunuza
* Mark spell as executed instead of deleteable to solve crash.
*** Source mangos.

**Its a big commit. so test with care... or without care.... whatever floats your boat.
