Merge issues processing

This change merges issues processing into the main routine for processing
log file lines.

Testing done:

Ran VDDReporter against a large dataset and checked issues output.
Read test log once only

This change removes the code from Suite that reads through the test log to
find the results line and then parses it to generate the test summary for
the suite page.  It is replaced with the code in test that already does
those tasks and some accessors for the data.  Now, the test log is only opened
and read once, and only by the code in Test.

Testing done:

Ran VDDReporter, looked at output.
