(Bug 5080) Grab all subjects and logtimes from a journal
(Bug 4980) XPost footer now links to OpenID page on current server.
(Bug 5184) Add additional interaction link props to TR
(Bug 5184) Use color props for management links
(Bug 5080) Separate out pruning logic into a method, and add duplicate detection

This is a best guess based on exact server timestamp and subject. If
both match exactly, we figure that this was a previously imported entry,
or maybe crossposted entry, that is not linked properly (as an import /
crosspost) for some reason.
(Bug 5184) Standardization of props

-sorted properties in standard order in TR
-renamed props per fu's suggestion in core2

(Bug 4980) XPost footer now links to OpenID page on current server.
(Bug 5080) Log when we skip an entry because it looks like a dupe

So we know what's going on. We had to move this below the existing
checks, so that we can log only if it's a guess (not if we're certain
beacuse it had been previously imported/crossposted)

Also adds error-checking for db issues.
