Subject: Add lint target for ant

Running "ant lint" will now run lint on the project, and dump out the
errors to the console as well as also export the errors to lint.xml
and lint.html int the bin/ directory.

This changeset also modifies the lint CLI to allow multiple
simultaneous result reporters - so you don't have to run lint twice in
order to get both an .xml and an .html report for example (which is
useful when you're running lint on a continuous integration server,
and you want the .xml file for the lint plugin trend graph and the
html file as a user readable report to click through to from the build
page.)
