PKEuS 188096665c Implemented support for rvalue references (C++11):
- Split up && when it is part of an rvalue reference declaration
- Added support into symbol database
- Current implementation sets Variable::isReference() to true also for rvalue references - they can probably be treated like normal references in many checks.

Changed behaviour of symbol database: Insert argument Variable of functions that are not implemented into SymbolDatabase::_variableList
