first attempt at adding a search for events. It uses the API with the stub parameter to search for events matching a keyword, parameter
Add apiPost() and fix apiGet() to send the correct headers.
Login functionality.

Login functionality.

Add true to session_regenerate_id() and also redirect the register action to the legacy app for now.
Add the Authorization header to apiGet too for consistency.
Whitespace tidy up and add some docblocks.
Store the client id in the config file.
Pass the access token to the model.

We don't especially want the model aware of $_SESSION.
Remove oauth_callback route from Application controller.

This is not needed as we use the User controller to gain an access token
from the API.
