Tutorial on MelonJS changes

[finaiized]

Below are all the changes. This commit is meant to replace the current tutorial.html file.

• Fixed some English grammar, random spelling mistakes, and slight touch ups to the language
• Fixed the many unclosed tags and added alt strings to fix all the validation errors.
  • As HTML5 is not actually used on the page, you can change the doctype to XHTML Strict if you want; it validates as well
• Tried to beautify the Javascript examples on the page, since they weren't aligned to the edge of the code box (just a nitpick of mine)
• Consolidated all the pre code blocks. Feel free to move to an external CSS file
• Small update to reference the most current version of software

Though I've spent a lot of time trying to ensure accuracy, something may have moved somewhere incorrect or I've blundered a typo. That's my disclaimer!

Thank you for the corrected tutorial, and I'll check that and merge it this weekend when I'm back !

Cheers,
Olivier.

Awesome, my first Github Pull request :)
Anyways, I'll be taking a closer look at it as well later, so maybe if we double-check together, then we can raise it to 2 for no reason at all and quadruple check. I know that doesn't make sense, but oh well.
