Engines rework

    - LibGuess support for far east language autodetection
    - Support for LibRCD 0.1.9 supporting ISO-8859-1 strings
    - Fixing wrong encodings names returned by Enca
    - Engine plugins naming scheme is altered
    - New API functions: rccEngineGetInfo, rccEngineGetAutoCharsetByName
    - Most of languages are no more hardcoded, but moved to the configuration
    - RCD engine is added to Belarusian language (I hope it should work)
    - Some encoding names are fixed in configuration
    - Support for external libiconv 
    - Support for libcharset
    - Find UI interface language from LC_MESSAGES locale
    - Simple compilation fix (Thanx to D. Panov)
