[Freeciv-Dev] patch: fix last known problem in settler teamwork

[Greg Wooledge <ic5035%tss1crs.amgreetings.com@xxxxxxxxxxxxxxxxxxxx>]

This patch fixes the last known problem in my settler teamwork patch
(which caused units not to "wake up" sometimes when teamwork tasks were
completed).

It also removes a pair of compiler warnings for the terrain transformation
patch (I neglected to define two functions in the appropriate *.h file).

This patch requires both the settler teamwork patch (which is already
in CVS, though I don't know if the moves_left problem has been removed
since I can't seem to connect to www.freeciv.org today), and the
terrain transformation patch.  Without the latter, parts of this patch
may not apply cleanly; but this is a simple fix, so it should be easy
enough to apply the relevant parts by hand if necessary.
