- Also added some infrastructure pieces for it such as the ITagHelperDescriptorResolver and the default implementation TagHelperDescriptorResolver which will be filled out in a later commit.
- Reworked some extensibility points to allow accessibility of the descriptor resolvers per offline discussions.
#111
- Added TagHelperChunk generation.
- Added CSharp visitors to understand TagHelperChunks and render corresponding C# code.
- Refactored some code in the CSharpCodeVisitor so it could be utilized in other classes.
- Added a CSharpFieldDeclarationVisitor to render declaration pieces for TagHelper's
- Added metadata to represent specific TagHelper code generation constructs.

- The visitor looks for TagBlock's that match registered TagHelpers and rebuilds them into TagHelperBlock's.
- Added the code generator and corresponding chunk for a TagHelperBlock.
- Added syntax tree specific objects & helper methods to create accurate tag helper structures.

This is a perf improvement of about 500ms for our razor code generation
benchmark on my dev box. That's about .8% of the overall execution time of
this benchmark.
This change will remove a bunch of unnessary allocations from the
parsing/code-generation path, and should improve responsiveness.
For reference Enum.HasFlags performs boxing of the enum value, and then
does a type comparison to see if the types are the same. This is
significantly more costly than a normal bitwise and comparison, and it
results in allocations.
.NET FX Team will not be adding Char.GetUnicodeCategory because it breaks layering. We cannot have a dependency form System.Runtime.dll to System.Globalization.dll.
