dev branch: port templates from master branch

Add a small program to iterate over the templates directory and
generate a go map of name to file data. This is so we can compile
these templates into the dex binary instead of requiring files on
disk.

Also add a Makefile rule to do this automatically.

Since we don't have a good strategy which takes a username and password
add a mock connector which implementes PasswordConnector so we can
develop the frontend screens.

dev branch: support the implicit flow

dev branch: fix oauth2 values and remove unused code

dev branch: run server tests at a non-root URL

As we've seen on master it's very easy mistakenly make changes that
assume root URL paths. Run server integration tests at a non-root
issuer URL to prevent this.
