XDoclet support

[Sachin Patel]

Any objections on me checking in the XDoclet jira (778) into a devtools 
sandbox so people can start working on it?

There also needs to be some work done in WTP as well as in the geronimo 
plugins so that the tags can get registered in WTP in both the xdoclet 
configuration panel and in content assist.  I can work on driving those 
changes in.

Sachin.
