Language AutoDetection Improvements

    - Fix: Loading/Saving range options.
    - Fix: Language AutoDetection. Using locale language instead of selected one.
    - Support for range options in GTK UI.
    - Option to control recoding timeout is provided.
    - LibRCC.h is updated (Translate, Spell, IConv).
    - Documentation is updated.
    - Add 'rcc-config' alias to 'rcc-gtk2-config' in spec.
    - Implemented concept of parrent languages
	+ The concept is used in language autodetection. The string in considered
	language is permited to have words from all it's parrent languages. 
	+ English is assumed to be parrent for all other languages by default.
	+ Russian is parrent language for Ukrainian and Belorussian.
    - No translation to english if translation between related (one of the 
    languages is parrent for another one) languages is failed.
