AppVeyor: don't test on Node.js 0.10
AppVeyor: don't test on Node.js 0.10

Node.js 0.10 includes npm 1.4 that suffers from race conditions. Node.js 0.10
is already tested via Travis and any Windows incompatibilities should be
caught by Node.js 0.12 & io.js testing. AppVeyor is way too slow to be running
three builds on each commit.
