caTissue (all), I-SPY: Wiki links in README

[vikasvm]

Change all wiki links to short urls.
For example, replace https://wiki.nci.nih.gov/display/CIP/I-SPY with https://wiki.nci.nih.gov/x/8QrO in the I-SPY readme.

This needs to be done in gsid, catissue-CAS, catissue-migration-tool, metadata-based-query, keyword-search, commons-module, catissue-security-manager, wustl-common-utilities, catissue-simple-query, catissue-utilities, catissue-participant-manager, catissue-idp-authentication-manager
