Added Project Settings elements to dialog.
I will stop updating of project setting components unless required
as this was just to ensure ease of development of dynamic setting
modules.

Since adding settings widgets requires additional components to
be installed, I will add a Plugin model in next commit to port
them too in the future.
Added Plugins setting widget for Project Settings
In this widget, installation of components (programming language
specifications for dnd, installed and running plugins, as well as
uninstall capabilities and author information (bug submissions?))
will be listed.
