StarCraft 2 Campaign Manager

Alright with this release we can already see a small number of campaigns downloading and working.

Known bugs:

• Perfect Soldiers never finishes installling - I am aware it has to do with Aureolin Eclipse not downloading or extracting correctly, but havent found the root cause.
• Downloading multiple campaigns will make the download progress go bonkers - This requires a major rewrite in my end, for the time being just download a single campaign at a time.
