Regression test for #1062.
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.
Selector conversion methods different naming.

boot.js calls use old name and are not updated yet
so the merge easily with the other PRs involving boot.js

Smalltalk side changed completely.
