Removing redundant trigger-object
Refactoring this important integration test to use testpackage, and some additional improvements:

- Embedded stuff to make the logic of the patch more clear
- Using regexp rather than route to filter out objects that are not part of Jamoma from list of objects to test
- Added j.mutesolo~ to the list of objects to test
- Help patches are now tested in alphabetical order, and it's much more clear which one is being tested.
- Each test run for 2 seconds rather than 5
- Substituted a combine object for sprint after having seen some suspicious crashes involving combine, regexp and osc
