Issue #9: Try to handle cases where malformed XML is returned by the server.

There appear to be cases where the data is not being scrubbed to be valid
and well formed XML.   This can cause situations where attributes are not
being returned as expected.
Additional unit test to make sure simple handles malformed xml.
Refactor main activity to use Relative Layouts.
Refactor the Movie Browser to use Relative Layouts.

Release version 0.6.2
Reset version to 0.7.0-SNAPSHOT
Remove extraneous drawables and convert some to gif

Gif compresses better than png, so where possible if there
are large savings use Gif instead.
Episodes and Movies use same layout

Remove the episode browser layout and re-use the layout for movies.
This reduces some complexity and allows for more consistency between
these screens.
Add Aspect Ratio infographic

Added aspect ration infographic to the Movies and Episode screens.
Removed the TV Rating from the episode screen as there are no good tv
specific rating logos in any of the skins we base this off.
