[Merge] lp:~phablet-team/gallery-app/share-from-selection into lp:gallery-app

[Ugo Riboni]

The proposal to merge lp:~phablet-team/gallery-app/share-from-selection into lp:gallery-app has been updated.

Description changed to:

Allow sharing from the events or photo view, while selecting.

There are a few problems left in this MR:
- the header should hide when the share peer picker is displayed
- currently no application knows how to handle shares of multiple media. however the share peer picker displays these apps anyway (facebook and messaging). for this reason the selection is only enabled when there's a single item selected

Additionally the share button in the header does not visually show as disabled, even though it is, this is due to a bug in the SDK: https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1369640
