Allow for multiple options in terms of JavaScript loading, placement & aggregation.

Example of how I would like my javascript to load

Load jQuery at the top. Whitespace compressed & minified or CDN source. Top load needed for inline scripts. If hosted local, put in separate dir for very very long browser cache lifetimes via apache rules.
Load the rest of the JavaScript without blocking. Aggregated & whitespace compressed & minified.
