First two patches for xspec 12.6

We received two xspec bug reports whose fixes were too late to include in the latest release. Patches are in the usual place.

12.6.0a XSPEC issues a fatal error if the swind1 and zxipcf models are both used within the same session. Our thanks to Matteo Cerruti for pointing this out. Report added on Mar 29, 2010.

12.6.0b When applying fractional systematic errors to multiple channels grouped into a single bin, XSPEC should multiply by the square of the sum of the binned channels rather than the sum of the squares of the individual channels. Our thanks to Mike Nowak for pointing this out. Report added on Mar 31, 2010.
