Version 0.5

There were some issues with previous versions, and I thank users for discovering them.
I had previously neglected spaced usernames, whilst the backup system was unusable for in-use files.
I have also added the option to completely remove "new" files in the "backup restore" process if the previous state did not require the files.

I do not have an x86 product to test the x86 installer yet, but it should function similarly, with the exclusion of the WOW64 file sections.
