Add flag to "test" command for automatically submitting if it passes tests

[anderswagner]

Sometimes, you're so sure of your code that you want to run kattis test and immediately submit the code if it passes the tests.

I imagine it could look something like this: kattis test -s problemname

And to circumvent the y/N on kattis submit, you could even have a force submit with: kattis test -fs problemname

This might all be compressed into a single command (test-submit) instead of flags: kattis ts problemname

This is possible (at least it is now, don't know if it worked before)
