Remove references to gwtexpui from dev documentation and license list

gwtexpui is now built within Gerrit, so it's no longer necessary to
separately clone the git to enable hosted mode debugging in Eclipse.

Update the Eclipse developer documentation accordingly.

Also remove references to gwtexpui from the release process documentation 
and the license list.
