Adds class PopupSwitchMenuItem, which is a two-state switch similar
to those in system status indicators mockups. Also adds class Switch,
which represents the switch itself, in case it is useful somewhere
else.

Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls
we still have. Also get rid of unused GConf code in ShellAppSystem.
A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,
and compiled at build time in data/ so that the Shell can be run from
the source tree. This also requires setting the GSETTINGS_SCHEMA_DIR
environment variable both when running installed or from source tree,
in src/gnome-shell.in and src/gnome-shell-clock-preferences.in.

It was previously possible to add a workspace above the maximum workspaces
limit by dragging an item to the "add workspace" button or using the middle
mouse button click.
Provide the user with feedback in the info bar when it is not possible to create
a new workspace or remove the current workspace.
