Added the possibility to priorize urlify language maps
This is useful if languages have different rules for the same character.
e.g. German: "�"=>"ue"
Turkish "�" => "u"
Updated phpunit to be able to run from project root
Added travis-ci support
Add test for priorized language-specific maps

Thought it can't harm to also include this feature in the tests.
