The sass sources now live in a project in GNOME, so they can
be used in multiple projects like gnome-shell-extensions.
Because of that, add gnome-shell-sass as a submodule and import the sass
sources from it.
The classic style is decidedly lower contrast than the default
style, so the high-contrast variant could prove really useful
here. However for now, just override the default icon style as
in the default session.

The default in gsettings-desktop-schemas has changed to not include
minimize and maximize to match the default of client-side decorations
in GTK+, so start overriding the setting to bring them back in classic
mode.
Currently, we start gnome-shell in classic mode by passing
--mode=classic to the gnome-shell command line. This --mode=classic
gets stripped away when the session is saved, which breaks classic
mode on subsequent login attempts.
This commit changes the session file to set the
GNOME_SHELL_SESSION_MODE environment variable instead.

Some default values differ between classic and normal sessions. We
used to implement this by overriding the shell's default values in
mini-extensions (or more precisely: reversing the shell's overrides).
Use a mode-specific overridesSchema instead, which has the advantage
that settings defaults will not change unexpectedly when extensions
are disabled/enabled (for instance during screen locks).

Classic mode should be visually distinct from the normal session,
so provide a mode-specific stylesheet which looks closer to the
familiar GNOME2 default theme.

With new items being added on the left, the top bar gets a little
crowded with the dateMenu at the center, so move it to its "classic"
position on the right.

The Makefile had two rules by which it could possibly have generated the
intermediate .in file (on the way from .in.in to .session) and it picked
the one that didn't contain the substitution for @libexecdir@.
Consolidate the rules into one that does all the needed substitutions.
