Just replace the tc_isle.grf/scn files inside the Anthology's data folder.  This
update restores the spitter's unique dinosaur actions (ie. frill unfurl and spit)

Please note:  If you haven't already done so, you need to download trescom level
update to restore the spitter's actions in both the trescom and tc_isle level as
the trescom's level update contains the 'Script folder'(which also goes into the
Anthology's data folder.
