@jdswinbank
Add capability to skip all tests requiring the DB.
609d2c2 
This means that if I

- Don't have any database set up; and
- ``export TKP_DBDISABLED=1``

I can get a clean run of the test suite:

  Ran 376 tests in 543.274s
  OK (SKIP=102)

(Previously, I was seeing many database connection errors.)

Well, there's a smoking gun — the error is coming from TestEphemeris because casacore can't find its TAI_UTC data table:

Out of time to look at this further for now. @gijzelaerr , I think (??) this data should be provided by the casacore-data package — any idea why it's not being found?

maybe it is outdated?

ah yes, this uses my new binary wheel of python-casacore, which isn't configured to look at the right spot. a .casacorerc (i think) file with the path to the casacore-data content needs to be created.

Almost right: it should be ~/.casarc. See description in casacore/python-casacore#181
