Conversion Script (to old .blend files)
Conversion: function to create action actuator in the child objects when needed
Fix corner cases in conversion file
Convert files to 2.66a, 'Fix #3 Introduction animation (the bird)' and
fix child action actuator bug.

NOTE: used a patched version of blender since T42512 is not yet
officially fixed: https://developer.blender.org/T42512

The following conversion script was run via this command:
for i in `find * -name *.blend`; do b266a -b $i -P ../conversion.py; done
