Subject: [PATCH] Rewrite the warning (and thus add more hand-holding)
 regarding the "insourcetree build warning" when attempting a build directly
 in sourcetree. Adds additional information on how to actually "unlock" the
 sourcetree again after an attempt to build in the sourcetree has been made.
