Added compilation of templates in ./custom/brand/tpl/**/*.html

[devgeeks]

This allows templates compiled from there to overwrite templates compiled from ./tpl/*/.html

Also found and corrected contact email branding and an issue that had caused some parts of the about view to not show even on the mail released app.

This is useful, and I will commit it. I have a small issue with it worth mentioning - it may deserve eventual attention, but isn't clearly a problem:

• unlike the other customization provisions, this happens in-place, while the other customization stuff only happens in device builds. For one thing, this means that tests and javascript-only compositions of the app (so, eg, it can be run in the desktop browser) will include the custom templates, but not the other custom stuff.

I don't see that this will cause problems, but might result in surprises for those (probably rare few) among that use the browser composition to test things, but is worth mentioning because it may have unexpected ramifications.
