Fixes: UC Browser Support + Minor Refactoring

Fixes:

• Corrects an issue detecting with newer versions of UC Browser. See: #63

Updates:

• Refactored the code into a smaller number of test cases. Seems to actually be a very slight performance boon.

Drops Support for Opera Next

Drops support for Opera Next - it's not really a thing anymore and supporting it was interfering with proper detection of Opera propper.

Blink Based MS Edge Support, Improved PS4 Support

Adds basic support for Microsoft's new Blink based Edge browser. Slight improvements to PS4 support.

Performance and Reorg

Performance Improvements!

I made a number of seemingly minor changes to the regular expressions that when benchmarked resulted in a nearly 3% performance improvement.

Reorganized directory structure to be more standard

Old Path	New Path
Source/	src/
Tools/	bin/
Tests/	test/

Warning: if you are directly requiring the PHP file rather than using composer this will be a breaking change.

OculusBrowser

Adds basic support and tests for OculusBrowser

Hotfix: Fixes Missing Constant

Adds support for Yandex.

---

v0.11.0 was deleted.

A cherry pick from an upstream branch went awry as it made use of a constant not currently defined.

This hotfix removes said constant.

Headless Chrome

Now differentiates between HeadlessChrome and Chrome.

Nintendo Switch Support

Adds Nintendo Switch browser support.

Net/Open/Free BSD support

It was pointed out that a number of BSD based OS's showed up as "Linux" which isn't accurate/correct.

This has been corrected with the help of @goshoo

Puffin Browser Support

Adds support for the Puffin browser which is growing in popularity.
