Typo fixes and chisel description updates

Small typo fixes in docs and minor (cosmetic) updates in a couple of chisels.

* spy_users: Add a space after the username to make output more
readable
* spy_ip: Update -T to -A in description to be in line with bef6091
* spy_port: Update -T to -A in description to be in line with bef6091

Update: It seems Travis CI build fails, because the test are hardcoded. Wouldn't there make more sense if the test files were inside the `test` directory and not downloaded from amazon? That way the developer that made a change, should also update the tests.
