Wiki (Updating, further ideas)

[DigiLive]

I've added pages to the Wiki to make it more clear how to use PHP-diff.
https://github.com/JBlond/php-diff/wiki

@JBlond Please review the pages and comment below.

Let's keep this issue open for a while, so users also can make remarks and suggest additions in here.

[JBlond]

I like the pages. Well done.

It might be worth to mention the CSS files to modify the HTML output.

[DigiLive]

I'll add a styling page, explaining how to style html- or cli output.

[DigiLive]

Styling page is added to the wiki.
Feel free to correct any mistakes.

[JBlond]

• We should add a link or a hint in the README.md to the wiki.

The marking levels are not documented yet.
