Tracking Ticket: Changes which break backwards compatibility from 1.3.2 to 1.4

(Imported from Google Code)
Rev 219: Several XML prefixes that were exposed as static variables for convenience (i.e. Util.DDMS_PREFIX and AbstractBaseComponent.ICISM_PREFIX) have been removed. They should now be pulled directly from the PropertyReader via:

PropertyReader.getProperty("ddms.prefix");
PropertyReader.getProperty("gml.prefix");
PropertyReader.getProperty("icism.prefix");

The intent of this change is to allow the prefixes to be changed programmatically, rather than requiring a property change followed by a JVM restart.
