API: Deployments listing

Pagination in DeploymentsController is switched off when the request
asks for XML representation.

Closes #174.
API: Deployments show action (not all information shown yet)

This implements the show action for deployments, so that deployments can
can be linked to and queried for very basic information. There is some
uncertainty about the rest of the fields (e.g. how to represent current
and available deployment states, which date/time formats to use etc.),
so those fields will be added later.

Closes #181.
API: Add deployments to entrypoint

Closes #180.

API: Deployments #index gives full resources

Both for /deployments and for /pools/:id/deployments.

Part 1/2 of issue #202.
API: Show hrefs of deployment collections

To distinguish between /deployments and /pools/:pool_id/deployments,
@pool variable had to be defined for deployment API #index action. There
was no apparent clearer solution. (I didn't want to go peeking into
params[:pool_id] from views/helpers. Checking if @pools has only one
element would not be enough either, because this situation can occur
even when listing all deployments, not just deployments of one pool.)

To keep things as unobtrusive as possible, the @pool variable is defined
only for XML response, to avoid defining a variable for HTML response
that would go unused.

Part 2/2 of issue #202. Closes #202.
