JBIDE-13487 : fix errai deployment issues

This fix is 3-fold :
- tells GPE to generate the errai classes in a WTP friendly folder
- removes non-existing sources from build classpath as it provokes NPEs
  and prevents Dev Mode from running
- Refresh Dev Mode generated folders so these resources can be publishes
  automatically on any WTP server the app is deployed to.

 The Dev workflow is greatly simplified for the user :

 * Dev Mode :
   - deploy app on WTP server
   - run as > Web Application on external server (fill in url and select
     entry point)
   - click on dev mode link to open in browser

 * Slow mode :
   - click on Google > GWT Compile
   - wait
   - Run as > Run on server
   - open browser

Cleaner fix for JBIDE-13599..

Based on snjeza's patch but witout hard dependency on dmr, with no
dependency on having properties set in pom (can run tests from the
IDE), more tests and fully functional ${foo,bar:default} syntax as use
in iin jboss.

Adds suport for ${foo}, ${foo,baz}, ${foo:default}, ${foo,baz:default}
for the site url in the discovery url mechanism.
switch from stable/juno to development/kepler as default site to use in Central (JBIDE-13767)
