Fixing Dial, Matrix, adding Mango remnants
Made NX Manager, colorizer, nx html attribute

Also moved some things around in template (getHandlers call), created
ability to set throttle time, and created nx.onload func out of
necessity. Nexus elements are now added to the page by writing a canvas
with an "nx" attribute set to "dial" or "toggle" etc. This update will
break everything but dial for the time being, but we just need to get
all the other objects into the new nx manager system.
