Load JSON without need of callback file, improve location parser with an async queue.
Add package.json
Merge pull request #2 from remixz/parser-tweaks

Load JSON with a callback file, and improve the location XML to JSON conversion.
Write the .callback.json files back out (so they can be loaded cross domain)
Update package, probably need to fix it up a bit to allow "nom install"
Code is example of how .callback.json would be loaded in remotely.
Put the .callback.json files back :)
Lets have some 'darkening' filters
Add in the brightness, contrast and saturation filters, in a fashion.
Bump versions.
