globbing html files

[acornejo]

Great plugin.

Currently I am doing something similar in my build process, and I wanted to switch to use requirejs-blob, but I noticed it does not have support to work with require-text.

In addition to loading "controllers//*.js" I also want to load "templates//*.html", but for that to work as one would expect the latter should be load through require-text.

Could you add support for this? Or alternatively, would you accept a pull request that implements a "globtext!" instruction?
