[pony-build] Some changes

[C. Titus Brown]

Hi all,

I've made some additions to pony-build.  The two main new features
are a "CopyLocalDir" build command that lets you copy local directories
into the build location (handy for debugging) and two new sets of RSS
feeds: all builds,

	http://lyorn.idyll.org/ctb/pb-dev/rss2/all

and

	http://lyorn.idyll.org/ctb/pb-dev/rss2/failed

All of the changes are here:
