[ccp4bb] Resolve to CCP4...

[Kevin Cowtan]

Is there any way on the CCP4 GUI to covert the free-R flag from a 
resolve mtz file (where 95%=0, 5%=1) to a CCP4 style free-R flag (where 
5%=0 and I don't care about the rest), while preserving the free-R set?

I can do it a number of ways - e.g. using sftools from the command line, 
but it seems to me that this is a common enough task that there should 
be an easy way to do it.
