Refactor complicated .json to separate .TOML for services and ChatPlug config.

In order to comply with pep8 we should move function names to snake_case

Hi!

I run python main.py and I'm presented with this:

Traceback (most recent call last):
  File "main.py", line 1, in <module>
    from facegram.facegrambridge import FacegramBridge
  File "/home/hammyhavoc/ChatPlug/facegram/facegrambridge.py", line 1, in <module>
    from .config import FacegramConfig
  File "/home/hammyhavoc/ChatPlug/facegram/config.py", line 1, in <module>
    import configparser
ImportError: No module named configparser

I'm not sure what's the problem as all the fields in confing.ini are ok. So I'll leave some of the output here (the remaining output it's related to my FB profile. groups, friends...).
xx = my e-mail
Output:

Logging in xx...
Login of xx successful.

How to use this?
