Bootstrap wysihtml5

Hi

I have added a new feature, a text editor for a textarea element, this includes a simple asset controller and translator. It is highly configurable as well

I have taken https://github.com/xing/wysihtml5 and compiled a version for twitter bootstrap.
I had been inspired by https://github.com/jhollingworth/bootstrap-wysihtml5 so forked it and configured it for ZF2.  to work with this project.
It still needs a lot of work needed to clean up the code and add more features but is OK for now and works in a basic way.
