Added change log file and fixed bugs in the NVDown source code.

- Finally fixed downloading on Windows XP! The program will no longer crash because it can't find the folder it was being told to download files to!
- Added checks to ensure that versions of NVDA higher than 2017.3 can't be downloaded on Windows XP.
