Administration of dashboard actions currently shows proposed actions as
well as resources mixed. This patch tries to improve how they're shown
making things easier for administrators:
Resources will be shown after proposed actions, never mixed.
Proposed actions will be sorted according to the order attribute.
Resources will be sort according the two attributes that define its
availability:
The number of supports required.
The number of days after the proposal publication.
Previously, action as requesting some action from administrators by
default. Now this flag is false by default when a new proposed
action/resource is created.
