upgrades react version to 0.10.0 and bumps react-meteor version to 0.6

Should be self explanatory. I've got it working locally.

I'm getting errors on startup because v0.10 of react-tools no longer exports a .React property, so this line from src/require-react.js leaves the global React variable undefined:

React = Npm.require("react-tools").React;

Do you see that in a fresh checkout on your machine?

Sorry, its working now. Had to change require("react-tools") to require("react"), which returns the proper React obj

Still need to depend on those packages in package.js, but I'll push some additional commits to fix that.
