Methods were introduced in r84057 which, unfortunatly was tested with
PHP errors disabled :\
Additionally add tests for the full Turkish alphabet based on an article
from Wikipedia http://en.wikipedia.org/wiki/Turkish_alphabet
As mentioned by Bawolff on code review, r83970 only handled case change
of the first character lacking full strings support.
This patch override the uc and lc methods for the Turkish language (tr)
using preg_replace() which know about unicode. Other possible choices
would have been:
- strtr() => outputs garbage
- mbstring => can not know we handle turkish and transform i to I!
I have amended the RELEASE-NOTES to reflect this patch.
Some new tests are added as well to cover the regular functions as
well as the specific Turkish overriding. Result in testdox:
LanguageTr
[x] Change case of first char being dotted and dotless i
[x] Language tr lower casing override
[x] Language tr upper casing override
[x] Upper casing of a string with dotted and dot less i
[x] Lower casing of a string with dotted and dot less i
Turkish has two different i, one with a dot and another without a dot. They
are totally different letters in this language, so we have to override the
ucfirst and lcfirst methods.

* Reject underscore in validation
* Still case unsensitive
* Corrected tests using underscore
Follow up r83160 which was a follow up of r82927 (language code validation)
A language code may contains the underscore character (be_tarask)
and might as well be upper case (FR).
Add tests for Language::isValidBuiltInCode() against some language codes
