runxds.py -a does not allow setting a lower resolution

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Manually edit XDS.INP to reduce the resolution (by modifying 
INCLUDE_RESOLUTION_RANGE). 

What is the expected output? What do you see instead?
I would expect to see the lower resolution cut updated according to the user's 
input.  What I see instead is that runxdspy just keeps the previous highest 
resolution.

What version of the product are you using? On what operating system?
XDSme 0.5.0.2
MacOSX 10.9
