[Templates] cvs checkout fails on case-insensitive fs

[Mark D. Anderson]

Btw, cvs checkout of tt2 failed on my os x laptop due to "TODO" vs. "todo":

# cvs -z 3 co Template2
cvs server: Updating Template2
...
U Template2/TODO
...
U Template2/templates/splash/tabsbox
U Template2/templates/splash/tabset
U Template2/templates/splash/text
U Template2/templates/splash/ttdotorg
U Template2/templates/splash/ttpower
cvs [checkout aborted]: could not chdir to Template2/todo: Not a directory
