[ 942894 ] Some config enhancements
As part of us using Draco on a project, we've enhanced
some of the project configuration options:

1. We created a boolean flag to indicate whether or not
a project should be continuously built. This allows us to
use a single Draco instance for continuous and nightly
builds.

2. We had some dependancies between the projects and
didn't want to fold these into a single project. So we
created a "triggers" config element whereby a successful
build on one project will start builds on other projects.

Please advise if you would like a patch for either of
these.

[ 914253 ] Pass Parms with dracocli
We have interdependent builds, so we use the client to
kick off builds that are dependent on the current build.
It would be nice if we could pass parameters to nant.
Right now we are having to use a state file in a known
location to pass info between builds.

We had to break the project up because it was taking
so long to build the different modules.
