Russian language & settings generation based on column type info

Hi! Just added russian language and made settings generation slightly more user-firendly (I think defaults of control types should depend on sql types instead using text input for each entry). Some things may not work yet so it can be easily dropped.
I see you are using mysql-validator for each dbms type. It will be better if this validator will extensible and depend on dbms type. For example,  postgresql have some types incompatible with mysql . So, I had to temporary add try/catch block to avoid crashing.
