[Hps-analysis] New WABs

[Bradley T Yale]

Some pure wab, tritrig, and wab-beam-tri are finishing here, using the new detector and various fixes:

Thanks a lot.

Unleashing it on the farm.

New detectors are ready: HPS-EngRun2015-Nominal-v5-0-fieldmap,
HPS-PhysicsRun2016-Nominal-v5-0-fieldmap.

This detector no longer has carbon fiber dipping past the beam plane (the
"third half-module" that Rafo saw), so WAB conversion rate should be
correct. None of the active material has moved, so there should be no
differences visible in reconstruction.
