updating to react-tools 0.8.0

Updated to 0.8.0, that and browserify since it failed to build on the previous version. Seems to work with my sandbox project.  Tests all seem to pass. 

Question about this though : 

<pre>
[react] Compiling test/fixtures/jsx/error.jsx --> tmp/dynamic_mappings/jsx/jsx/error.js
[react] Error: Parse Error: Line 9: Invalid regular expression: missing /
</pre>

This looked deliberate to me? Returning two nodes from render where only one is allowed, i put it down to, 'check it fails when supposed to'?
