Ivan Savenko 1aa391fdf8 Split CGeneralTextHandler file into 1 file per class form
All text processing code is now located in lib/texts.
No changes other than code being moved around and adjustment of includes

Moved without changes:
Languages.h           -> texts/Languages.h
MetaString.*          -> texts/MetaString.*
TextOperations.*      -> texts/TextOperations.*

Split into parts:
CGeneralTextHandler.* -> texts/CGeneralTextHandler.*
                      -> texts/CLegacyConfigParser.*
                      -> texts/TextLocalizationContainer.*
                      -> texts/TextIdentifier.h
