[COOT] coot for 10.4 and 10.5 intel

[William Scott]

I need a couple of people to volunteer to test this on 10.4 and 10.5  
intel machines:

http://sage.ucsc.edu/xtal/coot/coot-0.5-pre1-intel_10.4_10.5.tgz
This was made and kindly supplied by Geoff Franks

I liposuctioned it down to about 185 MB, so I am hoping not to have  
broken it in the process

It goes into /usr/local/xtal

invoke with

/usr/local/xtal/coot/bin/coot

in a clean shell
