Sugar depended on Rainbow for clearing the activity instance/ and tmp/
directories. But Rainbow is no longer used downstream.
- remove support for Rainbow,
- avoid race when creating directories; don't check they exist before we
create.
CHANNEL_TYPE_TUBES was deprecated since telepathy-gabble 0.17.25 and
is no longer present on modern distributions. This breaks collaboration
for _all_ activities, regardless if they use tubes or not.
Therefore, check if the channel creation failed due to support and allow
channel creation process to continue.
This patch fixes collaboration for the activities that do not use tubes
channel in modern distributions, but also allow to use tubes when running
on older distributions.

In Gtk+ 3.20, you need to use the css name to select elements,
rather than the gtype name. Therefore, these must be added.
The css name must be set before the class instances are created, as
it effects the class rather than the instance. This is why it must
be places after the class definition.
A rework of the TreeViewInvoker used by the journal and activity list.
Fixes a persistent journal entry palette that reappears in journal or
home view. https://bugs.sugarlabs.org/ticket/4918
Also fixes an over-sensitive journal icon; with the journal mostly
empty, rapidly move the mouse from the bottom of the screen into the
lowest icon and then out again. Before this patch, the palette was
shown. After this patch, the mouse must rest in the icon.
Changes made:
- override _ensure_palette_exists in parent class Invoker,
- remove reference to MouseSpeedDetector, it is no longer required,
- remove enter and leave events; they are for the TreeView as a whole,
and are not required,
- properly detect that None is returned by get_path_at_pos, when the
coordinates are outside the TreeView cells.
Not fixed:
- moving the mouse out of the journal icon invoker does not popdown the
palette, but it does when moving the mouse out of the activity icon in
the activity list; so this is a problem beyond the invoker,
Tested on Fedora 18 and Ubuntu 15.10.
Test cases:
- check a click will activate item,
- check a right-click will show palette,
- check a mouse hover will show palette,
- check a brief mouse passing will not show palette,
- check if mouse leaving palette will popdown.
Instead of getting the position of the mouse later in the code,
this commit uses the coords given to sugar by Gtk that say where
the event happened. This means that if the system is busy, or
the user is fast with the mouse, the palette will pop up where
they originally clicked.
