TinyMCE for projects

Related to Pivotal Tracker story *Mercury Editor for projects description* https://www.pivotaltracker.com/story/show/64507678.

[TinyMCE editor](http://www.tinymce.com/) for project description in new/edit form, using [tinymce-rails gem](https://github.com/spohlenz/tinymce-rails). My solution for initialization under Turbolinks is probably clumsy - feedback appreciated. It also takes away some of the flexibility of TinyMCE configuration and only allows the default layout specified in config/tinymce.yml.

To see it in action: http://websiteone-nga.herokuapp.com/projects/websiteone/edit.
on the other hand, Turbolinks is part of Rails 4 - that gives a hint that DHH considers it useful and well established.  Turbolinks follows the pattern of modern JS frameworks and does give and improvement when <head> is heavy.

I really do not see, how you guys find it complex or unintuitive.  All you have to remember, that <head> does not get reloaded and use Turbolink's events rather than DOM's.
