Added quotes to fix icepack.script problem on Mac OS X v1.0.0.d0003

[proteanplanet]

This small tweak fixes issue #174: "Bug in icepack.setup" :
When running on Mac OSX, the operating system allows spaces to occur in paths:
e.g. "/Volumes/Promise RAID/work/Icepack"
However, if icepack.setup is run from such a location, it crashes, because the lines:
set ICE_SANDBOX = pwd
set ICE_SCRIPTS = ${ICE_SANDBOX}/configuration/scripts
Do not allow for this occurrence. Placing quotes or parentheses around the second line fixes the problem:
set ICE_SCRIPTS = "${ICE_SANDBOX}/configuration/scripts"

Are the code changes bit for bit, different at roundoff level, or more substantial? BIT-FOR-BIT
Is the documentation being updated with this PR? NO
If not, does the documentation need to be updated separately? NO
Please suggest code reviewers in the column at right: TONY

Thanks Andrew. We're already too far along with the current release to add this in, but we'll test and merge it soon, consistent with our plans to have the latest-and-greatest versions available all the time. Just FYI.

Sorry for the late attention to this. I only discovered it today when running it from a different place than normal on my mac.
