Aria2 support (patch included)

[vx-toxic]

aria2c is much better downloader than wget, as can utilize multiple threads which make download process much faster

I am not fluent in Python, so please add aria2c utility availably by yourself or rollback to wget if aria2 is not installed

Here is working code when aria2c is already installed
