DEV-49489 Money transaction msgs use display names

Server 1.40 will be deployed before Viewer 2.1, and it sends more
extensive money transaction messages, so I removed all the old
crufty localization code.  If Viewer 2.1 connects to an older
server (like a dev grid) money transaction messages will be
English only.  This simplifies the code tremendously.
