What is new for packagers

New API has been added to telepathy-gabble and telepathy-salut to support the work on the collaboration framework, which results in needing 0.9.16 for tp-gabble and 0.3.13 for tp-salut.

One of the goals of the collaboration refactoring was dropping functionality in sugar that has been implemented in telepathy-mission-control, so Sugar now depends on tp-mission-control 5.4.3.
