--source and --include are mutually exclusive #265

Add a sanity_check function to CoverageConfig to perform sanity checks
after configuration values have been collected from files, arguments
etc.

Raise an error if --source and --include are both set.

The config tests are amended because some of them have both source and
include set.

Based on the original patch from Nathan Land

close #265
