LMD VCL - Unicode Support

General unicode support notes:

   * Use WideString instead of String (if library has ansi version, the use defines (see TLMDString type))
   * One symbol, in general case, isn't equal one byte - it's very important!!!
   * Use Unicode API function instead of its Ansi version. These function has W suffix. As example DrawTextW, ExtTextOutW etc.
   * For any operation on unicode string use routines from LMDStrings.pas (must be in core modules)
   * For unicode string lists use classes from LMDUnicodeStrings
   * Win 9x/Me has very poor unicode support and need to check all controls on these OSes.
