Task for Manveer_Basra: Merge all the activity downloaders and more
A task that includes a few microtasks:
1) Merge all actitivity downloaders into one program. Make it modular though, so it's easy to add new stream platforms. 2) Allow to pass all parameters via command line. I don't mean force to pass them, but allow to do so, for example 3) Write documentation in ccextractor.org (contact Carlos to get login info)
--platform=hulu --user=carlos --password=mypass
When not present read from config file. If the password is passed empty (--password=) or is not present in the config file, ask for it and read from stdin (but don't echo, of course).
