feat(RD): add texture pack downloader

This extends the resource pack downloader, with the custom behavior of
filtering the versions that shows up, to those <= 1.6. As always, Flame
is funky and requires a bit more workarounds than average.

This will also get a nice improvement when the Version parsing and
comparison PR gets merged! :D
