WIP - Adhere to PSR-*

[Crisfole]

Adds check for coding standards.

Address #77 by complying with PEAR (which seems closest to our current code which doesn't use Namespaces).

This is a WIP: there are 88 non-fixable style errors; mostly missing comments and a bunch of class methods in snake_case (which should be camelCase).

@Crisfole PSR-* is probably what you wish to comply with, rather than PEAR (PEAR will be dead pretty soon anyway) :)

@nocive thanks! Any chance there's a CodeSniffer config for it?

I wasn't thrilled with PSR's namespace rules in particular...it'd be a notable breaking change, and I'm not sure how to gracefully deprecate. It'd need to be a major version change (in which case there's more than one bit I'd like to improve).

adhering to PSR is the way to go moving forward imo, you don't necessarily need to comply with all PSR standards, but PSR-0 and 1 are usually followed by most php projects.
Sure there's a phpcs conf for it, here you go: http:https://cs.sensiolabs.org/

Gracias! Appreciate the link. 0 and 1 at least? Got it.

Sure, no worries, happy to help.
Feel free to mention me if you need more feedback.

I'll probably wind up doing this as a giant refactor which will definitely bump major version numbers...

I'm going to close this pull request, the PSR standards are in the refactor1.0 branch
