[rules-dev] Guvnor is now using GWT 1.5

[Michael Neale]

This means, if you are using hosted mode, you will need to download
GWT 1.5 (RC), and install it on your machine, then adjust your
environment variable(s) in eclipse to point to it, etc... (and the
build.properties if you need to compile it).

Everyone else can ignore it.

What it means is better support for Firefox 3, faster in general etc...
