Refactoring and updating

[NinjaLikesCheez]

Hey,

Please let me know if any of this isn't to your liking and I can change it! Also if this breaks all your stuff feel free to trash the PR and ignore me :)

• Removed sample JSON and rejigged file saving to work across UNIX (hopefully windows too - I can't test but should work)
• Added a config file containing API keys, data paths, default gamertags (for testing/pulling data)
• Moved each API section out to it's own class under PiousAcademic (sick name btw) e.g. PiousAcademic16807.Metadata()
• Added docstrings to some classes (not fully complete)
• Refactored samples (getmeta) to getmeta, getprofile, and getstats
• Tried to kill as many PEP8 warnings as I could

Looks beautiful - I'll go through some tests later to make sure things still run well but after a quick skim everything looks great; a lot better than my original mess (what was I thinking with one giant class for all the methods haha)

Thanks for the contribution!

Now lets hope they open up the bloody req apis!
