Header needs locked and visible properties

[Tim Peeters]

The header API proposal https://docs.google.com/a/canonical.com/document/d/1wUUKtPmRmwbUELC1BUB9l0VOAwS_zAPRSCqMopUxR1c/edit#heading=h.yv1xue68vkeu adds Page.head.locked and Page.head.visible properties that the developer can use to lock and show/hide the header. Several developers asked how to hide/show the header. Currently the header can be hidden by setting the title to "", but that causes problems, see https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1402054
Current locking of the header is done by setting Page.flickable = null, which is not very intuitive API.

We need to implement the proper way of locking/showing/hiding the header by adding head.locked and head.visible properties.

We would need this functionality to be available when dragging ListItems, to avoid header interference.
