Update SenchaTouch to 2.1.1

Updated framework by copying relevant files over a fresh app generated
with the new version. Now requires Sencha Cmd rather than Sencha SDK to
build.

Noteable changes: file structure has changed somewhat, scrollable property
needed to be changed to preserve rendering, did not update ListPaging
plugin because 2.1 version does not work with a DataView.
Fix build output dir to not change
Update sass - add required module for spinner and regenerate.
