refactoring of theme component
mail Demian Katz:
The refactoring project is now complete -- theme-specific view helpers have been moved into the VuFindTheme module, and reliance on the ServiceLocatorAwareInterface has been reduced by setting up dependency injection factory configurations in the default root theme theme.config.php.  I have also updated wiki documentation to reference theme.config.php instead of theme.ini.

Merge branch 'master' of git://vufind.git.sourceforge.net/gitroot/vufind/vufind into bsbvf2
