1485470	Setting locale to tr_TR breaks PHP	hayalci	till	"Hi,

There is an odd problem with Turkish language and PHP. To cut it short, in Turkish there are ""dotted capital I"" and ""dotless i"" characters, and ""i != I"" 

PHP calls strtolower() on function/class name before function calls. if the system locale is set to tr_TR, functions that contain ""I"" in their name cannot be found and called.

As roundcube sets locale to the selected language, using Turkish translation OR a browser which lists Turkish as preferred language is impossible currently. I get a white page and the following error in the logs. 

The error I got.
{{{
PHP Fatal error:  Call to undefined method MDB2_Driver_Datatype_sqlite::getDBInstance() in ./roundcubemail/program/lib/MDB2/Driver/Datatype/Common.php on line 1117
}}}

The attached patch fixes the issue by setting locale to ""en_US"" if user requests ""tr_TR"". This solved the problem and it worked with the Turkish translation of the interface. No side effects to non-Turkish users.
