Fixed SQL Injection
Removed syncing of xml to db

No idea why the mana server has to do this...
Manaweb parses the xml files anyway. So why not let it do it (if
somebody keeps maintaining it).
Ported SQL code to Qt
Ran qt-creators auto identation
Fixed issues after migration to QtSql
Added Qt dependency in cmake
Removed sql server depending cmake configuration
Removed obsolote comment
Bumped copyright year
