==================== Summary ====================

Name: MonticelloConfigurations-dtl.164
Author: dtl
Time: 14 April 2020, 7:20:07.551613 pm
UUID: e0f4a43a-1654-454c-9008-6ee483c29e58
Ancestors: MonticelloConfigurations-dtl.163

Limit the size of the MCM prior versions list, default length 10, to keep MCM file storage to well under 50k in size. Each version is identified by a UUID, so full version history can be reconstructed should the need arise. Also do better ordering of the user dialogues when storing a version.

  A MCConfigurationExtended is a configuration with author initials, timestamp, comment, and a list of prior versions. Its external storage format is organized for compatibility with MCConfiguration, such that an image wtih support for only MCConfiguration can use configurations saved from a MCConfigurationExtended. The intended use is to enable documentation of configuration maps, and to allow modifications to a configuration map without loss of version history.!
