--skip and --todo and deprecate --exclude

[Munter]

The skipFilter option lets a programmatic user match against properties of a tap-report before the test is run and skip the test by returning true.

The todoFilter option lets a programmatic user match against properties of a tap-report after a test has failed and mark the test at todo by returning true.

Added --skip CLI option that takes strings and does naive string matching against a tap reports values and returns true for any match. This is sent into skipFilter

Added --todo CLI option that takes strings and does naive string matching against a tap reports values and returns true for any match. This is sent into todoFilter

Deprecated --exclude CLI option
