Driver Downloader: Hotfix & Support the new definition format.

[RedGreenBlue09]

Driver Downloader stopped working because:

• Lumia-Driver got updated recently which the definition file format is changed.
• GitHub removed support for Subversion.

Both happens almost at the same time. That means most of the foundation the downloader depends on is now removed; Developing an alternative method takes a lot of effort.

The good news is, after nearly a week of hard working, I have finished the rework of it, which enables it to work again. Check it out here.

Please note that the drivers that it downloads are untested, and it actually have some regressions:

• You need to have Git for Windows installed.
• It stopped working on directories that have =.
• Error handling is unimplemented.

I implemented a workaround in 92be187. We still need support for the new definition format, no ETA for that.

GitHub disabled SVN support. At a result I need to switch to Git.

Edit: Git for Windows is way too bloated to be packaged into the installer. Instead, I'll use the power of aria2c to download all files.

Edit 2: It's impossible to download the files with aria2c because the file names in the INFs is case insensitive while downloading with direct links is case sensitive.

Fixed in DD 4.0.
