Restore ability to recompile android libs
tinyxml redesigned for "const wchar_t *" support

as a result:
1. "const wchar_t *" more "native" to haxe nme strings then original
"const char *"
2. removed many back and force utf8 conersions for TextField html
3. fixed many multi-language problems on windows platform (cpp) for html
text
4. commented useless tinyxml methods for load/save xml which should
simplify crossplatform code support.
