Title: Can any?

Check if the user has any of the permissions on any of the resources
```ruby
can_any? [:create, :destroy], [Project, User]
```
Return true if any of the actions is accepted for any of the
resources. You can check for one action in several resources, like:
```ruby
can_any? :update, [Project, User]
```
Return true if the user has :update permission on Project or on User
Or, you can check for several actions on a single resource.

```ruby
can_any? [:update, :destroy], Project
```

Return true if the current user any of the permissions on the given
resource.

Or even checks a single permission on a single resource

```ruby
can_any? :update, Project
```
