Add PropertyGrid to Design dialogs

[bparks13]

For all custom dialogs, there is now an added tab that contains a PropertyGrid to display all properties for a device. This is always the non-default tab, so that the priority is on the custom GUI, but it is always present should the user want to look at and change any properties that are not exposed via custom controls.

Any changes made in either the custom GUI or the PropertyGrid are operating on the same underlying object, which is the object attached to the PropertyGrid, so that all data is always synchronized.

As we discussed during live code review, please move the ProbeGroup editor into the the specialized stimulus waveform property editor on the RHS stim gui so that the base class does not have to be informed about its existence.

Per the live review with Aaron, I will be changing this to utilize DataBindings in addition to using the event hooks to enable easier synchronization between the propertyGrid and the custom controls.

Im doing a quick user level exploration of this and noting some stuff that im finding. First issue:

1. on the hs-64 optical stim dialog, there is no magin on the Define Stimuli tab
2. The pulse period and x axis on plot dont have the same units (I thought I fixed this by redefining stimuli in terms of frequency for optical stimuli in some other commit, maybe that has not been pulled in?)

On Neuropixels dialog, it looks like some properties dont have an Acqusition/Configuration category attribute:

Please do general check for this

I understand why the the Properties tab exists here, but its very odd because it looks like its the same "kind of thing" as a probe and also

1. redundantly exposes a lot of probe configuration properties.
2. has clickable ellipses on the Probe Configuration property that don't do anything

I would prefer something like this:

I cant resize the properties pane to see to text on it:

Overall, I like the properties panes. Can you please have a look at the above issues before a proper review. Also take care to ensure that OOP and idiomatic programming principles are being followed before I look at the code.
