Couple of (PSR-1) improvements

[bjornpost]

Awesome move to refactor this! I've prepared a pull request which does the following:

• I've removed the included license in every file as there's already a global LICENSE file.
• Improve usage of whitespace to comply with PSR-1 (maybe missed a spot or 2).
• Add type hinting for a couple of functions (@wimwinterberg made a start with this in his fork).
• Force usage of SSL/TLS as suggested in Remove non-SSL option #6.
• Rename a couple of classes and functions to be StudlyCaps and not StudlyCAPS.
• Fixed an issue which caused performGet(multi='raw') to return the constant data instead of $data.

---

Sidenotes:

• I think we can dump the included autoloader function if we force composer (which is the entire purpose of the project I guess).
• If there's a roadmap/todo list I can help getting things off that list.

Thanks @bjornpost I will look over this tomorrow and merge. Also, I agree with tagging initially since this will break things.

Trying to trigger a travis CI build on this, but I can't seem to get it working.

Did you flip the switch for this project in your Travis CI profile?

Yes, it is building fine for the branches and PRs now. However, I only added the automated travis builds after you had submitted this PR.
