keep the default reasonable. Also change the config loader

In addition to switching URLs for individual JIRAs
to point to issues.apache.org, also construct alternative
URLs for JIRA reports (usually 1 per release, summarizing
the issues fixed in that release).
There is some inconsistency in which releases have associated
JIRA reports. For releases where we never published a link to
a JIRA report, I added a <keydef> tag that could be used to
construct a report in future, but didn't fill in any URL.
Some releases do have a link to a JIRA report in the release
notes, however the report is empty. Possibly there was some
strangeness around the release process for those, or there
could be some missing info in the JIRA system. I just
transcribed the links in those cases and didn't try to
reconstruct the history to debug the empty reports.
