Add support for custom InfoSectionBase ui

[rmbryla]

Currently if you want to add section in the SelectedInfoUISystem you need to add another InfoSectionBase to the sections list. Without additional work this just puts up a red "Unknown element type" banner. At the moment im not sure how to hook into this manually so I dont have a ton of details on how this could work. Something like CompanySection or ResidentSection is setting values in some view but I cant find where that is.
