Confidant

* Added a feature to disable the credential conflict checks; see configuration
docs for IGNORE\_CONFLICTS

* Added support for sending basic webhooks; see configuration docs for
WEBHOOK\_URL

* Update statsd depencency from 3.1 to 3.2.1

* Switch to doing semver in a more proper way. Though generally all previous
releases were backwards compatible, we had been releasing features in point
releases rather than minor releases. Going forward, breaking changes will be
in major releases, features in minor releases, and bugfixes in point
releases. When dependencies are updated we'll consider the impact of the
dependency update to determine the semver release
* Made the XSRF cookie name configurable. See the configuration docs for how to
changet he XSRF cookie name.

* Move scripts into the confidant module to be able to use the scripts when pip
installed

* Added changes and settings for better performance in confidant. See the
performance section in the configuration docs
