Add support for setting 'showCompoundNames' in Content Blocks Plugin

In content blocks 1.11.02, a configurable feature was added to show compound names as item titles.

See
http://content-blocks.forge.onehippo.org/cmsconfiguration.html#Show_the_names_of_the_block_types

Essentials does not support setting this yet, and can only start doing so if 1.11.02 is part of the release pom, estimated in 7.9.6
