Port To TelepathyGLib

[Creatune]

Worked after porting.
@pro-panda @tchx84 @quozl please review :)

I used:

as reference.

Tested, activity isn't shared and logs show.

The error suggests the activity may not have been tested for collaboration after a port to GTK 3; it will be necessary to fix and test that before or during port to TelepathyGLib. It should be a simple change to use get_shared_activity, if I recall correctly.

G'day @Creatune, do you plan to finish this pull request?

[quozl]

Thanks. Tested. Collaboration doesn't share any application state. Logs contain;

How did you test collaboration, @Creatune?

[Creatune]

I did not test yet. I am still figuring out how to set up a collaboration environment. This was just a hunch of mine. I will let you know when I complete the setup. Sorry for the inconvenience.

[chimosky]

@Creatune you can setup another vm and use that to test collaboration, run both vms and check the neighbourhood if you'll see two instances - check both -

Hi @srevinsaju. I am currently busy and will start contributing in March. You can take this over if you want.
