1.0.6 wip

Commit for Issue #20
Here's how the default backend page looks with font awesome: 
http://kiss.bg/yii-boilerplate-dev/backend/www/

There's some code good for YiiBoilerplate too:
In commit https://github.com/Yasen/YiiBoilerplate/commit/a4ddd2c20b70fd44a3b6efb795e9d0d846919a6b
it's worth looking at the changes of common/config/params.php and common/extensions/bootstrap/components/Bootstrap.php 
They define glyphicons of font-awesome and include the css (either minified or normal version depending on the YII_DEBUG variable). Hope this makes sense. Thanks.

Edit: On a side note, I think it would be good to merge YiiBoilerplate and YiiBooster. I know that Booster is within Boilerplate, but in the case of font-awesome integration, changes were needed in both applications and I thought having changes in just one would be better.
