mkwineprefix: Very simple tool for generating the initial wineprefixes with sanity checks
ditch: Remove chunk size limitation, finally

It occured to me (derp) that the problem wasn't in fact with curl but
that sed couldn't open a file that surpassed maxium length (255 bytes).

Given this realisation I switched ditch to use mktemp instead of using
the url as the filename (derp).

Now I can finally just use the actual limit twitch sets which is 100,
yay...
