Switched to a simpler capture command configuration

While before you needed to write your own capture plugin, now you can
just modify the command used for capturing which makes the configuration
much easier.

Switched to pycURL

Instead of calling cURL from commandline to ingest the mediapackages,
now pycURL is used. Additionally, all components which used httplib and
urllib before now use pycURL as well.
