Fix: Delete status label. With color coded progressbar, status label is not necessary
Fix: Regex and stylesheet update is not done instant, thus setting progress bar to default color before parsing log will cause a ~0.5 second green progressbar. If input text do have errors, this is misleading.

Add: 3 more tests for progressbar color. (These tests have to be done separately. Combining them into one test will somehow not show the correct result. I have tried reload GUI and resetting codechat option but still not work)

Add: One unit test for log parser. (Need more log parser unit tests)
