Improve speed for first completion list to be displayed.

The first time TypeScript's getCompletionsAtPosition method is called
it can take 1 to 2 seconds to complete. Instead of making the user
wait the first time they trigger completion in the text editor the
addin makes a call to getCompletionsAtPosition when the project is
opened.

A better solution would be to move the completion to a background
thread so the project load is not slowed down.
Fix copyright on headers.
Use the LanguageServicesCompiler when compiling on saving a file.

Using the LanguageServiceCompiler with the an existing
TypeScriptContext, which has already processed all the files in the
project, makes compilation of a single file on save much faster than
before. Previously it was taking a second or more and there as a
perceptible delay when compiling.
Allow both compile on save and on build options to be enabled.

Previously enabling one option would disable the other.
Rename classes to be consistent with TypeScript.
Use the LanguageServiceCompiler when building the project.

Compile all TypeScript files using the LanguageServiceCompiler before
the project is built. Using the LanguageServiceCompiler with an
existing TypeScriptContext, which has already processed all the files
in the project, makes compilation of a single file on save much faster
than before. Previously a new TypeScript compiler was created with
all the project files added to it, including the lib.d.ts file, and
then the overall compilation would take over a second.
Re-enable folding.

Fix typo in method name.
Implement compile on save.

Allow both compile on save and compile on build to be enabled at the
same time.
Add scripts to addin.xml.

Include missing scripts so the .mpack now works with Xamarin Studio.
