remove dilib

[TanyaStere42]

Context

In an effort to clean up the base directories, we discovered that there is a major dependency between the dilib .jar and the spotmapping algorithms Dilib is no longer supported, and we don't have strong documentation around its usage. We want to remove this from the system if possible.

Feature sign-off requirements

• Remove all taglib references to http://www.sunwesttek.com/di (donationthanks.jsp, individualDistanceSearchResults.jsp, SimpleCmRSpecifySession.jsp, encounterSpotVisualizer.jsp, spotMatchingAlgorithm.jsp, web.xml)
• Remove dilib .jar file (and the local repo that contains nothing else)
• remove the di: functions for the images and spots created
• pages all build successfully, tomcat runs

Added context: we are working to retire the spotmapping algorithms
