0.3.1.7 release

Somewhat overdue, done in a hurry to get the just mentioned fix out:


Changes since 0.3.1.6

• Changes suitable for working on microcrystals - reachable through a -microcrystal command line flag, and -failover is probably helpful too.
• If lattice or spacegroup specified, do not run tests.
• 2dr and 3dr now the default pipelines - use 2dold or 3dold if you need to get to the old pipelines.
• Fixed selection of known lattice in IDXREF reindexing.

Please get in touch if you would like more information on the microcrystal option - this is definitely work in progress...
