Have removeCombined remove templates as well as JS

[MartinLogan]

It appears from running an r.js build with removeCombined that the text! prefixed defines do not get removed from the build directory.

I'm scanning through thr code to see if I can create a pull request for this, but wanted to check whether it is intentionally like that or not.

Yes, definitely a weakness right now: the issue is that loading via plugins is opaque to the loader, the loader does not know what files are involved with a plugin load, but I do want to allow plugins to opt in to the remove behavior. I am tracking this as #344, so will close this bug in favor of tracking any discussion or changes in that bug.

Thanks - I'll follow the discussion - the separation seems correct and it sounds like the correct way to go is to make the plugin responsible for communicating that the resource is disk based and can be cleaned up.

Really enjoying working with r.js.
