Metpx-sarracenia

* if a publish fails, retry forever, do not give up (result of major
outages) probably fixing a regression.
* added exponential backoff to publish retries.
* improved testing on travis (unit tests, static flow, dynamic flow) more to
come.
* sr.py now prints an error message when it fails to find an include file
(used to crash.)
* extraneous log messages cleaned up.
* catch a timeout exception that happens when the app is sleeping, not a
bige problem, not worth a major error message (sr_poll)
* if we get a message about a newer version of a file, call it new if
mtime is newer, or if checksum is useless (0, random, name) use
checksum as last resort.

* more debug code needed to be removed (introduced in b3), this time with a functional impact. (try/except had been commented.)
* correcting the release name (get rid of errant i in 2.20.01bi4) discovered after publication the i made the rest of the month inaccessible on launchpad (build error if not lexically higher than previous build). so borrowing from February now. Versions: v2.20.01b5 and v2.20.02b1 are identical. only incremented because launchpad refused to build the package.

* bugfix: there was a crash in sr.py when logs aren´t named as expected.

identical, but had some problems with publishing, so re-released with a new tag.
