Add a preferred mirror option to yum-plugin-fastestmirror

Description of problem:
When using yum-plugin-fastestmirror, it currently selects only the "fastest" mirror.  I have a mirror available to me that does not count towards my download quota, and I would prefer to use that one if possible, even though it might not be the fastest.

Version-Release number of selected component (if applicable):
Name        : yum-plugin-fastestmirror
Version     : 1.1.22
Release     : 1.fc11

How reproducible:
Always

Steps to Reproduce:
1.  # yum clean all; yum list updates
  
Actual results:
yum-fastestmirror selects the fastest mirror

Expected results:
yum-fastestmirror selects the mirror I want it to use if available.  If my preferred mirror is not available, or I don't care what mirror it should use, it will continue to use the fastest mirror.

Additional info:
Patch attached.  It only supports a single preferred mirror.
