started to implement a page object model

WIP
created a scrolling views home page

bumped version to 1.2.0

starting to work toward organizing the app into home pages with table
that reveals content
removed briar_features/core && tabbar because these were testing briar predefined steps

this is in advance of deprecating all the of the predefined steps
migrating to the page model while trying to test UICollectionViews

complicated commit
refactored Tables ==> Scrolling Views tab with a table menu

moving the app toward a 'Home Page with Menu' from which users can
navigate to controllers with related views (buttons, text, pickers,
tables/scroll views etc.)
disabling that rotten test that was expected to fail @allow-rescue is not working
disabling collection view testing until the server/gem is updated (0.9.167)
doing some tag filtering for device profiles in cucumber.yml

pluto cannot support collection views
neptune w/o launch cannot support email views
RubyMine updates
bumped the briar gem to 0.1.3.rc1 for mere mortals
Rakefile does a better job reading device sets and now reads an iOS specific file
new rake task for opening the most recent report file
test cloud rake task is xtc - was tc
updated the docs
Merge pull request #3 from jmoody/1.2.0-collection-views

started Page Object Model on the ruby side and switching to a tabs + menu approach of laying out the app
