C# can be colorized by its HTML context

[michaelblyons]

C# in a <%= block will take on any scope colorization from the HTML that contains it. Thus, injecting content into HTML attributes will have the string scope from the attribute value for the entire block:

<div class="thing1 <%= someBool ? "thing2" : "thing3" %>">
    The whole C# section would have `string` colorization.
</div>

This is the same issue as sublimehq/Packages#643, and now that clear_scopes is in the non-dev ST3, we can take advantage of it.
