C++0x support macros

[David Nolden]

KDevelop already can do all of these complicates things, like deriving
the type from all kinds of expressions (-> see class
ExpressionParser).

The main issue about C++ 0x support will be supporting the new syntax,
because the parser is really complicated, then integrating it with the
already existing facilities, and then also providing some proper
code-completion in the added syntactic cases.
