Moved Issaquah issues to Pending status
Simplified setting status through bash scripts

The common pattern to move status on a block of issues is now:
   list_issues OLD_STATUS | set_status NEW_STATUS
This hits a problem when NEW_STATUS has embedded whitespace,
so the work-around for now is to turn whitespace into under-
scores, and reverse the transformation inside the set_status
tool.  This should be possible through appropriate use of
quotes and similar in bash, but has proved the better of me
so far, so opting for the quick fix.  Suspect there may be
similar problems with handling the Windows command line as
well.
Shell script to aid mass-status-updates

This script allows us to pass the issue number argument resulting
from a list_issues query as the first parameter to set_status. In
hindsight it might have been easier to re-order arguments in the
set_status program, but this is a quick-and-easy fix before we
make the command-line parsing of our tools smarter.
