Reverts part of 109b369199
Good idea in principle, albeit the hardware gets in our way. In
synaptics 1.4 two-finger emulation was enabled by default on devices
that reported finger width but had to since revert this. The hardware
doesn't really separate width and pressure, so a hard tap off a finger
gives a high width, a wide finger gives a high pressure on light
touches. We got spurious right-click presses when two-finger
emulation was enabled.
Now we have the control-center providing a checkbox for two-finger
emulation but it doesn't enable emulation, which to the users appears as if
two-finger scrolling is broken
(https://bugzilla.redhat.com/show_bug.cgi?id=738123).
We now disable the checkbox again for hardware that doesn't do two-fingers.
it's not reliable and we're likely to see further bugs when the spurious right
clicks take effect

libcommon.la defines several new GTypes, so it cannot be loaded into the
same process multiple times.
Copy gconf-property-editor to libgnome-control-center as this is useful
for all panels. However, it will need to be converted to GSettings in the
near future.
Copy capplet-stock-icons to the mouse panel, as it is not used in any other
panels.
Remove references to functions not yet implemented for panels (help,
window icon, etc).
