Merge pull request #205 - Decompilation of lifted operators

This decompiles the C# generated code for lifted operators back to the original short form.
This can result in a significant improvement to the readability of the resulting code in some more complex functions because C# generates 2 temporary locals for lifted operators that can now be inlined.

As a byproduct the following improvements are also included: more thorough boolean logic decompilation; various project/solution file improvements; Ldloca support for variable splitting; simplified shift operators (already in icsharpcode branch); significant performance improvement for stack analysis of variables to offset the added complexity from ldloca support; decompilation of compound assignment with overloaded operators; some type analysis refactoring.
