Add support for include_objects and exclude_objects parameters

[viniciusam]

It could be a comma separated list:

-include=obj1,obj2,obj3
-exclude=obj1,obj2,obj3

Ex:
utplsql run ut3/ut3 -exclude=betwnstr,award_bonus

Nice, just make sure it works with schema named objects too. Also, think If it would be better to push this down to the frameworks API, so that it makes the API even better.
