Add Elementary switchboard integration

[Manish Sinha (मनीष सिन्हा)]

Activity Log Manager has gnome-control-center integration. Just like g-c-c there should be an optional switchboard integration such that activity log manager acts as a plug

[Sergey "Shnatsel" Davidoff (shnatsel)]

Quoting Manish's letter from the mailing list:
"Right now activity-log-manager (alm) can run as a standalone tool or
as integrated in
gnome-control-center. The build system takes care of it.

In src/activity-log-manager.vala there is a VBox named ActivityLogManager

1) When creating the switchboard plug, the same codebase, a separate
file can be
added which uses this VBox to populate the plug

2) Then the build system needs to be altered to build this plug
optionally since alm is used
in many other environments too

If someone from elementary team can get (1) done, then I can do (2)"

Assigning ~elementary-driveby to take care of (1)

I believe this was fixed a while ago. Either way, I see Privacy in Switchboard so that's that.

[Andrea Basso (voluntatefaber)]

Cody, well, that's not said, because it's probably the gnome plug ATM and in the long run we may wanna have only "native" plugs, not GCC stuff.

The current branch has broken support for switchboard integration. Working on it

[Manish Sinha (मनीष सिन्हा) (manishsinha)]

Finally everything works. Phew!

The build system auto-magically detected existence of pantheon and builds the switchboard extension. This automatic build can be suppressed by passing --without-switchboard
