MessageSource_MySQL does not save untranslated strings

[rabol]

MessageSource?_MySQL does not save 'new' strings unless you have a valid record in the catalouge table for the specific language.

In other words, you need to make sure that you have a messages.XX (where XX is the culture) for each culture that you would like to use - before, the messages.XX record is not automatticly created as with XLIFF

Provide your own custom db message source to handle this. The DB versions of message source are trickier to support.

hmm... It is not possible to add a custom messages

MessageSource?_Db will be added later for 3.1 branch such that MessageSource?_MySQL and MessageSource?_Sqlite will be deprecated.
