[Server, UI] Group Project properties WMS options, for readability

PR Description:

Well, I'm not a big fan of this dialog which often looks to me like a succession of options added over time, with no logic of coherence in user experience or "let's put checkboxes on top and other widgets types below" (see e.g. how the geometry related options that should be close are spread over the dialog). At the same time (or as a consequence?), the docs is also not quite helpful to get connections among the options.
This PR, within the limits of my understanding of the docs, tries to group close options together, mainly depending on the type of request involved (GetFeatureInfo/GetCapabilities vs GetLegendGraphic/GetMap/GetPrint). I know some options are involved in more than one request and, since I'm not a server user, this is just a starting point to help find appropriate distribution and groups names

As usual, a Before vs After
