Heroku Sentry Release

Trigger a release in sentry from heroku. A workaround for getsentry/sentry#15722

Note:

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

is part of a scrollable region that has been scrolled, its coordinates will
be different than if the region hadn't been scrolled.

This method corrects for scroll offsets all the way up the node tree, so the
