* Changed SendMessage to explicitly use SendMessageW for unicode
* Added cancellation of main thread (hopefully secure enough to not throw an exception but it's not that important)
* Switched from reading the console log one byte per character, to multiple bytes, if necessary
* Adjusted count in struct, since apparently it has to be byte count and not character count (adding 1 for the null-byte wasn't necessary)
* Changed string to be marshaled as UTF-8 so that it shows correctly in-game as well
