Squashed 'NRefactory/' changes from 2200240..a92606c

a92606c Some improvements to output visitor.
136fd88 Fix some parser issues.
41b4385 Port NRefactory to .NET 3.5.
3b6fe6f Adjust resolver to AST changes and disable failing unit tests.
93e9d1e Use implicit conversion operator to convert from Pattern to AST nodes.
b37ea77 Re-enabled the unit tests that were commented out.
defd426 AST bugfixes.
60d4fe9 Add pattern matching for query expressions. Pattern matching should now work for the complete C# AST.
