politeia v1.3.1

This patch release includes the following fixes and improvements. See the
changelog for the full list of changes.

• Fixes a MySQL maximum placeholder bug. MySQL allows a maximum of 65,535
  placeholders to be used in a single prepared statement. This limit was being
  hit on a recent proposal vote that had a high voter turnout, causing certain
  clients to be unable to cast votes during the last day of voting.

• Makes various small improvements to politeiavoter. A signal interrupt bug
  and a bug that was causing unnecessary retry attempts were both fixed. The
  --hoursprior UX was also cleaned up.

• Fixes a performance bottleneck on the proposal list views. v1.3.0 added a
  API request to the proposal list views that nearly doubled the list view load
  time. This release reduces the response time of this call by ~86%. The
  proposal list view performance now matches the pre v1.3.0 performance.
