Rearchitecture Project Manager Screens Workflow and Create Project Settings Ctrl

* Renamed UX screen files and classes to include screen in the name

* Changed screens to emit a screen change request a controller can connect to

* Made ScreensCtrl that owns and manages screens and their changing and history

* Made Project Settings Control managing back and next buttons

* Add Project Setting Model and moved New Project Settings Ui into Screen file

* Goto previous screen always works

* Removed unnecessary QObject namespace from connect calls

* Merged ProjectSettingsModel into ProjectInfo
