OMG THIS IS SO NICE! Use the same code to edit DBs in setup and admin.  

use angular events for a much cleaner implementation of our form stuff that avoids a bunch of dependent code.

tidy up the way form messages are handled.  it's now just a single <span> element for either error or success.

update all the admin resource templates to use updates css classes for Form-input and Grid stuff where appropriate.

basic version of new Database details page using full form validation.  this is a WIP and not complete.

tidy up our angular DatabaseEdit controller and remove statically coded values from frontend and pull it via form_input endpoint.

move /frontend_client -> /resources/frontend_client to make sure the static resources are bundled in our jar files.
small updates to main routes.clj file to make static asset serving from "resources" instead of "files", which allows for serving out of jars.

because of copypasta. 'Add Database' now allows you to specify the type
of Database (postgres or H2)
