Merged #2230: Fix using "having" with bound params in CActiveRecord::count()
"CActiveRecordTest::testCountWithHavingRelational()" has been updated exposing issue #2201
Added unit test file for CHttpRequest for the methods
parseAcceptHeader() and compareAcceptTypes().
Modified the regexp in parseAcceptHeader() to accept wildcards in the
path.
Modified the description of compareAcceptTypes() to better reflect the
comparison result (higher preference returns lower value, so that most
preferred is first in the array).
Merge branch 'master' of git://github.com/yiisoft/yii into 2131-add-accept-header-parsing

Merge from upstream.
