* [Win32,WinRT] Fix listFiles and listFilesRecursively use unicode.
1. Incorrect convertation to unicode
if (length != fullpath.size()) correct only ASCII char.
2. For convert unicode exist api, to avoid errors.
3. Equal first char on '.' - error
Need check full name file on "." and "..", otherwise exclude file and
folder begin '.'
Now not use macro UNICODE, for easy use unicode convert api(Otherwise,
you need to connect different versions WinRT and Win32).
