Replace "WindowsTemplateStudio" references with "TemplateStudio"

[mikebattista]

Need to update ico filenames, template manifests, code comments, schema names, licenses, etc.

[mrlacey]

Note that needs to also include the common abbreviation of "WinTS" and the "Wts" and "wts" prefixes that are also used throughout the code.

wts. is also used as a prefix in the template tags. will this be changed too?

Also, "WTS" is used in the generated code to distinguish TODO comments that are created from the templates and those that are otherwise included. Should these be changed too? (So TODO WTS:... would become TODO TS:...)

[mikebattista]

Yes I want to replace all of that. I already updated comments and things in my template update branches and was waiting to refactor the template schema until you merge your work. I don't want to do that twice.

Finish what you need to so we can merge your refactor work then we can work on this together.
