- Added a new system to show an error if old events are used
- Removed `test_data.json`, since I don't want to risk that anyone
accidentally commits their username & password
- Finished work on `sendEmoji`
- Split `_send` into two parts:
`_getSendData` and `_doSendRequest`, which allows for an easier way of
adding new send requests
- Changed `test_data.js` to `test_data.json`
- Added `deprecated` decorator
- Added `deprecation` function
- Readded old functions, and marked them as deprecated
- Changed parameters back to being type-in-specific (support for python
2.x)
- Deprecated `info_log` and `debug` init paramters
