src/goCover.go: add go.coverMode to display coverage data and counts

Provide an option, go.coverMode, to change the value for -covermode.
Provide the option for the user to display borders around covered and
uncovered code. These are named 'coveredBorderColor' and
'unocveredBorderColor' and default to the same colors used as
backgrounds. The boolean option go.coverShowCounts show how often each
block of code was executed by the tests.

Fixes #256.
