Bump stic version to 0.6

Output
------

* Display number of failed checks in tests on fail
* Display <setup...>/<teardown...> on failures there
* Display number of failed tests
* Display number of skipped tests
* Use singular "check" for 1 failed check
* Write "1 test run" (not "tests")
* Don't capitalize stic label in test's output
* Always print test suit name in output
* Drop extra empty line from output

Integration
-----------

* Make test failure report compiler-friendly

Compatibility
-------------

* Use rand() (not random())

Performance
-----------

* Skip test fixtures without checking every test
* Don't run {setup,teardown}_once when no tests were run

Fixes
-----

* Make stic work when tests are defined with suite
* Fix skipping test header
* Fix qualifier inconsistency for one variable
* Fix buffer overflow
