Add user edit action to the user controller

[visto9259]

There is no user edit action in the user controller when the logged in user can change its data.

There is not much data that is editable in the base User entity. The objective is to have the building blocks to support application specific customizations like views, forms, services, events, etc.

Work to do:

• Add route for edit: lmcuser/edit
• Add edit action to the User Controller
• Add edit form
• Add edit view
• Add update service to User Service, with pre and post events
