Fix Apps "documentation" text

Problem/Motivation

Clicking on the "Read documentation" link for Apps emits some kind of configuration file with text which needs a lot of cleanup.

Proposed resolution

Fix the spelling, grammar, capitalization, punctuation, and formatting (ie, spaces after comment delimiter). There might also be a need for further explanation of items, if this configuration file is intended to also be the only documentation for Apps.

Remaining tasks

Reading, editing, spell checking, correction, polishing with a fine wax, covering with plastic.
