Fixes #2597. Enables standard glyphs to be set via ConfigurationManager (#2595)

* initial

* basically working

* removed test settings

* removed extra usings

* Improved API docs

* Renamed glyphs to be consistent and use unicode names; use char literals

* Refactored Glyphs class & Json format to not be static (startup perf)

* Refactored Glyphs class & Json format to not be static (startup perf)

* Fixed a bunch of API doc errors

* Switched checked/selected to glyhps from box drawing range

* Switched button glyphs to nicer looking ones that seem to work on standard fonts

* Upgraded LineDrawing scenario

* CrossHair->Cross

* Fixed unit tests

* Fixed unit tests; moved Glyphs from Application to ConfigurationManager; added CM global using alias

* Found and replaced all other special glyphs; fixed more unit tests
