[#137] Display filters before validators

- Since they operate before validators, makes sense to display them first, too.
[#137] Fix verbiage on toggles

- Toggles should read "Yes/No"
Rebuilt UI distribution
Merge branch 'hotfix/137-order-of-inputs'

For #137:

- Display toggles using "Yes/No" terminology
- List filters before validators
New agOnEnter directive

- Execute the given expression when an enter key is released.
- Push focus to given input when a keypress is given to the input.
[#137] Fix form definition(s)

- Moved main form declaration to only include the input filter definition
- Placed a form around the "new field name"/create combo

Fixes the issue with pressing enter on the new field name input
Submit name change on enter

- When a name change occurs, and the user presses the "enter" key, validate it
  and update the view.
- Fixed validation logic in input filter controller; was always invalid, as it
  was checking the submitted name against... the submitted name!
- Modified ag-edit-inplace to use ag-on-enter for the input; required pushing
  the submit logic into the scope.
- Removed debug statements from ag-on-enter directive.
[#137] Fix modal dialog "<esc>" key usage

- For modal dialogs we want dismissable, added the following attributes:
    - data-keyboard="true" - this is technically the default, but good to be
      explicit
    - tabindex="-1" - this was needed to ensure that the modal gets keyboard
      focus when raised, thus allowing the escape key to work. See
      http://stackoverflow.com/a/12630531/31459 for details.
- Updated to Bootstrap 3.1.1 (did this before discovering the tabindex fix, to
  see if the behavior was fixed in a later version of bootstrap than we were
  using)
Rebuilt UI distribution
Merge branch 'hotfix/137'

Fixes #137

- Hitting enter for a new field name creates it
- Hitting enter for a field name change validates and finishes the action
- ESC button now closes modal dialogs (except FS and Cache check)
- Toggles use "Yes/No" terminology
- Filters now listed before validators
