XDocs proposal with attribute requirements

[Jesse Stockall]

I've added some new @ant.task tags and modified <antdoclet> to generate 
the required vs optional information for Ant task attributes.

There is still some work to be done on the html generation (dvsl) side 
of things, but the all information is there.

The generated documentation and code modifications can be found here

Comment and suggestions are appreciated.
