Update gitignore with ctags files for gems
Create the TaggingsPresenter and use it in ViewingTaggings

* The spec for rendering taggings in viewing_taggings_spec.rb:23
	is not specific enough. It's difficult to test it well, because of
	view_context being triggered twice, and the specific parameters
	structure being too much of an implementation detail.
Improve styling
Update .gitignore with sublime-project related files
Rename ViewingTaggings to ViewingTaggableTaggings
Resolve feature spec with js not always passing.

  * adds a short sleep time (0.1s) to 'bip_select' implementation
    to fix random race bugs when testing edit-in-place selects.
Temporary revert to using numeric quantifier_values in taggings_presenter

* The prettier version using more graphical display
	makes the spec fail.

* I prefer to temporarly defer the implementation of this
  more graphical display.
