Substantial refactoring.

Added datatype defaults.properties generation as well as xdocs for them. Created wrapper task somewhat similar to Darrell DoBoer's in mymidon (although his is still slicker!).

Since its already processing all of Ant's main source code, I added in generation of todo lists of both Ant and this proposal - into two separate directories.
