Fix(main, taBind, textAngularSetup, globals, taTools.spec): Immproved the issues with html and model getting out of sync

  Also corrected issue under Firefox where the initial selection was before all the content
  - globals: improved stripHtmlToText() slightly
  - main: fixed a mistyped if in switchView()
  - taBind: small formatting changes for clarity
            improved element.on('keyup') code
            element.on('focus') now detets an bad selection condition under Firefox and fixes this
  - textAngularSetup: added a coverage comment in recursiveRemoveClass() that is now needed
    because of changes to taTools.spec
  - taTools.spec: Changed the test set 'test clear button' so that now the whole
                  htmlcontent is now never selected.  This was an issue beacuse when
                  all the htmlcontent was selected this triggered the element.on('focus') fix
                  for Firefox and broke the tests here.  All the tests now run properly.
                  The biggest change was to now wrap the test content in a <div class='test-class'></div>
                  which caused the expected values to change.
