Transform current implementation into regular Coffescript classes
so that the same call method can be reused on the dispatcher
as for other classes.

Corrected div id for profile password/edit
Added first spinach tests

 Fixed a test that was looking for an outdated HTML ID

per changes with slack, they’re now using “static” web hook urls that describe the team & service with IDs that don’t change if the team or service name change. their recommendation is to use the raw webhook_url instead of building it out of components to allow more flexibility

this should also prevent issues cropping up with mistakes in how the urls are parsed

Always delete repositories from the filesystem when deleting a project.

Updated some tests to match new IDs

to the reset password view and the change password view after first login.
Updated JS to work with the updated views.

Fix 500 error on login page if ldap enabled and sign-in disabled
