Message:

Fixed completely broken national (non-Latin1) character input in Odin. There were two problems:
1) When translating OS2 WM_CHAR to Win32 WM_CHAR in UNICODE mode, ANSI->UNICODE conversion of the character was not done.
2) When hosting windows on threads created with CreateThread(), characters in WM_CHAR were wrongly converted from OS/2 codepage to ANSI codepage while they already were in ANSI due to the message queue begin switched to it at thread startup.
3) The main thread's message queue is now also switched to ANSI at startup so the conversion from step 2) should normally not take place now.
