RFE: Automatically check tickets for common mistakes before allowing users to submit them

[cooljeanius (Eric Gallager)]

For example, if the component is "ports" but you left the "port" field blank, it could prevent you from filing the ticket until you fill in the "port" field. Or if you leave the "cc" field blank for a port that isn't nomaintainer, it could remind you to fill it in (even better, it could check the maintainer field of the port itself and automatically fill it in for you). Or if you're submitting a portfile, it could automatically run port -v lint --nitpick on it and prevent you from submitting it if there are any errors or warnings. It could also submit the portfile to the buildbot and let you know if the buildbot fails to build it, kinda like how some GitHub repos have Travis CI integrated with their pull requests. My idea for submitting this ticket originally came up in IRC when larryv was wondering if the "priority" field could be hidden for certain users.

Now that MacPorts has pull requests on GitHub, lots of these things are already implemented on the GitHub side of things... not sure how many are worth bringing back to the Trac side...
