  Yii code style correction
  Removed unnecessary spaces.
  Transferred data for unit tests from the test functions into data providers.
  Undo accidental permissions change on bootstrap.php
  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).
  parseAcceptHeader() function description tidy up.
  Typo corrections and code tidy up.
  Altered parseAcceptHeader() to use only one regexp. Thanks to Ka on StackExchange for this expression.
  Typo corrections
  Separated out parse and compare functions. Reduced regular expression count to 2 from 3. Modified MIME type array map structure.
  Added #135 back in changelog, which got lost somehow..
  Moved position of line to follow numerical order.
