- Russian Engine is really renamed

    - Translate to English is fixed
    - Default charset for "all" languages
    - Support for per-class additional and dissabled charsets
    - Use 'GetSomethingNumber' instead of 'GetSomethingList'. 'GetSomethingList' functions are depricated.
    - rccUiGetSomethingName gets id's on the input instead of names
