[For 1.6] jSnippets 1.0 (jQuery & JS Manager)

[combus]

I know it might be a lot to ask, but will probably help you a lot to manage your javascript in a near future. It seems like you currently have a lot of javascript files loaded on your theme, so I would recommend moving this JS files to jSnippets as snippets. That way you don't have to edit the headerinclude every time on every theme, you can just manage your JS file links (or whole code) from jSnippets, and even decide what scripts are applied to each theme.
