Also, is_admin and can_create_group are exposed in the user information.
Fixed attributes_for_keys to process properly keys with boolean values (since false.present? is false).

s 3599: Add snippets_enabled flag to projects for API

Replace missing comma

Add api to collect owned user projects. Api deploy_key.create: Enable deploy key if it exist in other owned project

The API docs incorrectly referenced a few attributes associated with users. The 'blocked' attribute has been replaced with 'state'. Also, 'dark_scheme' seems to no longer be available in the User model so it should be removed from the exposed attributes in the API User entity.

Add color scheme ID to API User entity

 * Closing #3066
 * Closing #3609

Since it's now an integral part of the project name, it should be
visible via the API.

Also added tests.
