C++: Type deduction for auto-declared variables implemented

Browse Source 
Handled to major cases of 'auto' variable declaration:
1. auto var = someInitializer;
2. Q_FOREACH(auto item, collection) or foreach(auto item, collection)

In first case type deducted directly from initializer. If variable has no initializer then corresponded error reported. In second case type deducted from '*collection.begin()' expression.
