Add Settings View

[eboileau]

Aims/objectives.

We have an empty Settings view to go with User > Profile > Settings. We need to add functionality.

A clear and concise description of todo items.

• [x] Display account settings (currently user name or email)
• [x] Allow users to change password
• [x] Display projects and dataset (priority?)

As for the last point, the plan is to display a list of a user's own project requests (with status e.g. pending or approved), which will allow him to know if a request has been accepted or not, and to track his requests. We can also display a list of his dataset (those that he has uploaded). This would be relatively simple to implement, but we would need new DB tables e.g. to associate Project and Dataset with User, and a table for "project requests".

Re last point: we first need the data structure, see #89
