Fix Url Matching for similar patterns

[cebe]

currently the order in which available languages are defined influences the way URL patterns are matched,
if I specify en before en-GB the matching will always find en in the URL but never en-GB. Changing the pattern to match
longer patterns first fixes this.

fixed the travis build by adding output_buffering=On option. Otherwise tests that include session handling were broken.

@cebe Thanks, I'll have a look.

Regarding sessions in tests: Weird, we already used sessions before. Did the default phpunit version change again in travis?

@cebe Could you also fix the README? There's a note about language order here:

I think this is because Yii Request component now complains if you want to set headers but headers have already been sent. Without output buffering enabled this will cause errors in console environment like in unit tests.
