requirejs JavaScript snippets.

Added 2 snippets: for the define and require functions.
Moved RequireJS snippets into javascript.snippets.

The two snippets are at the end of javascript.snippets, and the javascript_requirejs.snippets file has been deleted.
Make class snippet PSR-0 compliant

When making a file classes ViewHelper.php, you would expect the classname to be ViewHelper, not Viewhelper.
Replaced 'RequireJS' with 'AMD'.

These snippets are more general AMD snippets, rather than being specific
to RequireJS i.e. they can be used by anyone using an AMD script loader,
not just RequireJS.
Remove space between function declaration and arguments list (jshint complains too)

JSHint complained about 'Unnecessary semicolon'.

JSHint complained about the semicolons at the end of the for loop
snippets, so I've removed the semicolons after the for loop closing braces.
