Fixed macro calls on search and categories, added description to theme.

Hi Gaurav, I tested your theme against Roller trunk, a couple of changes needed but it looks really good!  I changed the license text below, the license is not for the *theme* but for the articles written by the blogger and thought the Apache license is too lenient to be the one used OOTB (of course, the blogger can change it as he desires) so reverted to the one used by Fauxcoly.

The theme.xml has a new "description" field (ROL-2015) which gets placed above the preview image when the new blog creator is viewing the theme options.  I've linked your blog to it, as you can see below -- is that OK with you?  If the theme gets put into Roller people will be seeing it when they scroll to your theme.

Finally, be careful to use space-only padding (no tabs) when doing work that can go to an Apache project.  (2 or 4 spaces for XML/HTML, 4 spaces for Java.)  Thanks, Glen.
