Adding a justintv component. Fixes #13
Porting generic decoder
fixed usage of deprecated functions listenWith and connectWith

Hi,

Beginning with python twisted 13 the deprecated functions listenWith
and connectWith were removed. This prevents flumotion from being used
on current Ubuntu releases and will be unusable with Debian Jessie.
My attached patch fixes the problem.

Use hashlib instead of the deprecated md5 library.
Removing the _PatchedModuleImporter hook.

The _PatchedModuleImporter didn't pass through the level argument which is
needed for the future absolute_import to work properly.

```python
from __future__ import absolute_import
