Fixed how the cross origins headers are added. They are now globally added. Need to look into how it should be done

Conflicts:
	ConfigRemedy.Api/Bootstrapper.cs
	ConfigRemedy.Api/ServerStartup.cs
Updated how the Cross-Origin headers are applied. Using "pipelines" in Nancy
Started on UI with a boilerplate setup
Began with a new UI
Updated the environment model with some more fields and added PUT to /environments
Removed old client
Started a GUI. Very hacky for now, but CRUD on Environments work

Code quality is horrible, but it's a start. :)
Restructured how applications, settings and environment relates.

Environments and applications are now two separate documents.
An application have several settings. Each setting may have 0 or more overrides.
The setting now has a default value that can be overridden in a given environment.
Started work on UI for managing applications and settings
