[Feature] Option to add test coverage percentage to output

[deefdragon]

I currently have my tests output a covere-file to know how much Ive covered my code. It would be really cool to
1: Have an option to include that file getting generated automatically and or
2: Then parse that file for a coverage percentage to include in the top level output display data. (Passed, Failed, Skipped, Coverage% for each package/total)

It would require parsing the file to determine what percentage has been covered, but it would be helpful to know. That said, unsure if its THAT worth to spend time parsing the file.

Two asides.
1: This is the format of the output file,
<FILENAME>:<StartLine>.<StartCol>,<StopLIne>.<StopCol><Space><ReleventLines><Space><Covered/Not (1/0)>
2: There are also integration tests that have coverage support now, so it may be worth considering when implementing.
