List support

• Added support for ordered and unordered lists.
• Updated README, notes on version 2.00.0

Paragraph support

• Added support for paragraph breaks, converts double newlines from quill insert into a new p tag, the
  feature is not yet bulletproof, I need to take another look at my parser.

Autoload

• Updated composer.json psr4 definition

Image support and PSR4

• I'm now only testing against PHP 7+. [Tests]
• Added tests for setting attributes. [Tests]
• Switched to PSR4
• Minor change to API if using Quill (Render) class, after the PSR4 change I didn't like Quill/Quill.
• Basic support for images (outputting the base64 directly via src="")

Set the HTML tags to use for Quill attributes

• Added the ability to set the HTML tag for the following Quill attributes, bold, italic, script, strike and underline. [Feature]
• Minor rework to Quill class to allow options to be set, parse() was being called before the new option value was being set.
• Updated readme, now shows direct usage example.

Bugfixes

• The parser code no longer checks the default HTML tags, it checks against the type of tag in case a tag is updated.
• Removed redundant code

Simplified API

• I simplified the usage of renderer ready for additional output formats, instantiate Quill class to use renderer and then simply call render().
• I have finally moved to PHPUnit 6.

Note: The Quill class does not expose the ability to override options, that will be added in the future.

Headings

• Added support for headings. [Feature]
• Newline and paragraph support removed. [Regression]

Script:Sub and Scipt:Super

• Added support for Quill script:sub and script:super, issue raised by @ajaymeena

Links

• Added support for links. [Feature]
• Refactoring, simplified how attributes are replaced.
• Additional tests.
