- coloring of redmine severities
- fixed mistake in original tarantula code where deciding severity
colors by comparing tracker_type with first letter capitalized even
though passed in as lower case
- added database function to redmine interface to get status name from
status id of bug (need the name of the severity because it is used for
comparison when filtering to create the defect analysis metrics)
- added database function to get author name from author id for red
mine interface with tarantula bugs (need to check this, doesn’t seem to
be working)
