Override jboss-tattletale.properties with Ant project properties

[twogee]

IMHO, it would be convenient to use Ant project properties with a certain prefix (say, "tattletale") to configure Tattletale.

In my current implementation, this prefix is hardcoded. Perhaps it would make sense adding a "propertyprefix" attribute to Ant task?

Well, there is the 'configuration' attribute atm, but I don't have any major problems with adding the Ant property approach. However, the key prefix shouldn't be hardcoded as you say.

I do think that the 'configuration' should be considered the primary use-case though.

'configuration' points to a separate file, my idea was to have it all in build.xml

Anyway, <report .../> accepts 'propertyprefix' now (defaults to "tattletale").

Ok, sounds good. Remember to update the documentation as part of the pull request.

[twogee]

I updated the documentation, albeit I lumped several changes (partial extraction, component analysis, refactored reports, title option and configurable Graphviz output format) toghether.

Do you think we need separate threads to discuss the last two new features?

[jesper.pedersen]

Keep the documentation changes part of the PR which adds/changes functionality.
