Downloading from mutiple domains concurrently automatically

[korn7809]

Lets say I have 5 manga from site A, 5 from site B, 5 from site C and 5 from site D. I want it to automaticly start downloading from each site. The limit of how many manga being downloaded from each site set by an option seperate from "Max simultaneous downloads". This would help download a large number of manga from multiple sites while avoiding possible spamming of a single site.
