Michael Meeks f05302c3df lok: encourage more sharing of config Node pages.
Profiles show lots of probe:do_wp_page events from things like
configmgr::Access::getUnmodifiedChild - as when we read we touch
lots of Node reference counts - un-necessarily.

So - reduce un-necessary reference counting thrash here in the
lok case through the environment variable. Quite possibly this
would also be safe and beneficial for the desktop app - needs
measurement.

measuring with coolmap and an empty hello-world.odt before & after:
before:
	unshared  3634 (14536kB)
	unshared  3631 (14524kB)
	unshared  3605 (14420kB)

after:
	unshared  3578 (14312kB)
	unshared  3613 (14452kB)
	unshared  3599 (14396kB)

Not hugely encouraging, perhaps there is another page touch
underneath we'll find when this is addressed.
