Request functionality: commandline throttle setting.

[winkomaniak]

Would it be possible to add a command line argument that would allow user to set a minimal throttle? like --throotle 30 for 30sec throttle?

Reasoning:

Build in download profiles are fine for getting last few pages of webcomic. But for dowloading all of it it feels like one should download way slower out of respect for the comic author/host. Having it as commandline would allow user to not have to edit download profile files for each comic by hand.

EDIT: Also i might be doing something wrong but some downloader types seem to ignore session.add_throttle ?
