Restructure! QSettingsWebEditor transitioning to an Object for classes to possess.

QSettingsWebEditor now only presents 1 page, that of the current QApplication’s org:app.
The httprequest path no longer affects which settings are displayed/edited.
QSettingsWebEditor no longer has it’s own qsettings.
Security added: only the QApplication’s org:app can be edited.
Webpage is not generated until the httprequest has ended, allowing updated settings to be immediately reflected.
