During mass refactoring in In-Portal 5.2.0 I've noticed, that ".svn" and
"CVS" folder are scanned for template. Since SVN stores a original copy of
each folder's file under ".svn" folder it made theme scan work 2 times
slower, then it could.
Same problem was fixed in mass template compilation code.
