Add support for remaining asset types in Asset Studio Wizard

This changeset ports the remaining graphic generators from the HTML5
version (notifications, tabs, action bar), and hooks up wizard support
for them.

It also adds unit tests for the generators which generates images and
compares them to known good versions. I ran these tests comparing them
to the output from the HTML5 version of Asset Studio and all but 3 of
the images varied less than 5% (and I verified the remaining manually
and they're all fine and the difference is due to the images being
aligned slightly differently.)

The icon wizard is now also hooked up to the "New" button in the
Resource Chooser for drawable resources, and this changeset also fixes
a few related issues ("New" didn't work for file-based resources, and
newly created resources weren't showing up in the selection list.)
