Temporary fix of #1062.
Bumping nodejs supported engines to ">=0.10.0"

Node 0.8's npm fails to works with "^x.y.z" version specs
(= compatible with x.y.z), which some components already use.

Other than that, amber should work fine wiht node 0.8,
but bumping it anyway.
Moving st selector -> property name conversion to boot.js.
