tikal.sh now runs from symlink; ln -s /Applications/Okapi_0.34/tikali.sh /usr/local/bin/, then tikal.sh if /usr/local/bin is in PATH

If you create a symlink of tikal.sh in /usr/local/bin which is part of PATH, and invokes tikal.sh by just typing the script name, you get:

This code change makes it possible to invoke the script from a symlink. The change is provided only for macosx0x86_64 because I don't have access to other platforms and lacks time to test the same fix on those platforms but I believe the same fix should work for deployment/maven/data/okapi-lib/tikal.sh and deployment/maven/data/okapi-apps/cocoa-macosx/tikal.sh.
