DOMLauncher is now js library independent.

Themes are treated as full html pages.  No more .load() into the page.

Theme developers must reference link the cordova js file, and other
plugin/function links in their head.  This opens up to not needing to
load every plugin or no need to use the custom js plugin wrappers if a
developer does not want to do so (plugins and their wrappers are library
independent).  All file link references can be relative, no longer
needing a full file path.  Removed SDCard check since activeTheme.txt
works as the check.

To change themes, open up the text document and place in the exact name
the folder a theme resides within.
