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).
PHP CodeCoverage tests for class existance which causes Yii autoloader
to include non existent files.
Fixed by disabling Yii autoloader relying on include path
