Changed indentation, switched to logging, removed user-agents, change…

…d filenames and more

This release (v1.4) brings a lot of under the hood fixes and changes. To make the code more readable, these files are now following a slightly altered form of pylint. Tabs have been changed to spaces. All debugging is now done using logging() instead of print(). The filenames have been changed to better represent their function. A lot of these changes were suggested by @RoboticMind who [opened this super-useful issue](#3).

All user-agents have been moved to the config file as suggested by @jellysnake in [Issue #4](#4).

And last but not least, some comments, the PM template and reply template have been altered slightly.
