Improve website

Hi @b4dnewz,

The website is set here : https://glayzzle.com/

And the gh-pages of php-parser are available here : https://glayzzle.com/php-parser/

On this repository we could just provide a summary page presenting contributors, and next a list with a link to each projets.

We could start with the following projets :

* php-parser
* doc-parser
* php-writer

And some in-progress tools :

* php-reflection
* code-sniper

Also some experiments or related projects :

* grafine
* hack-parser
* codemirror-linter
* php-expressjs

What do you think about this ? Next each project will be able to live inside the website more easily.
