Add per-target CFLAGS variables to applet Makefiles to fix build errors
when objects are created with and without libtool.

Fixes #416

Properly anchor the popup menu to the applet widget to fix the menu
appearing in the center of the screen under Wayland.

This enables Wayland compatibility. Out-of-process applets use
GtkPlug/GtkSocket which is X11-specific and doesn't work in Wayland
sessions.

The default build remains out-of-process for backwards compatibility.

This applet allows the user to set the active power profile
(power-saver, balanced, performance). It's compatible with the
power-profiles-daemon and tuned, which are the same DBUS interfaces that
GNOME relies on for power profiles.
