Initial clean-up for the yab .hpkg 

I changed the #! line for all the example yab programs and for the IDE templates. the #! line should be:

#!yab

instead of:

#!/boot/home/config/bin/yab


as the yab binary may not be in /boot/home/config/bin. it may be in /boot/home/config/non-packaged/bin or /boot/system/bin


This lets the OS find the binary file for yab.
