All: Remove remnants of "twentyeleven" theme

This theme was developed by forking the built-in "twentyeleven"
theme. Not much was left of it, other than:

* confusing function name prefixes
* unused apply_filters() hoook.
* unused utility functions.

I've converted hooks to inline closures, and utility functions
to the jq_ prefix and moved to the appropiate file.
