System dialog can load directory from network path

[wbwakeman]

What's the problem this feature will solve?
Load annotation.json file from network path.

Describe the solution you'd like
Ability to paste in a network location in order to select an annotation.json file at that location.
e.g.
\allen\programs\celltypes\workgroups\tppd\Tissue_Processing\Cell_Prep\Cell_Locator_Dissections\20191001_487984.003

I suppose if I were on a Linux or MacOS, I would also want to use paths like this:
/allen/programs/celltypes/workgroups/tppd/Tissue_Processing/Cell_Prep/Cell_Locator_Dissections/20191001_487984.003

I want to view the annotation that another user has made and saved to a network drive. Currently, I need to mount that network location on my Windows computer, and then select each folder until I get to the one containing the json file.

Alternative Solutions
none

Additional context
If I load a file from a location, and then I click 'load' to load another file, it would be great if the file select widget opened at same the location where I loaded the previous file, rather than from my Documents folder again.

This is tracked by #105 and fixed in ab03e56

Looks like I can do this now. Suggest to close this issue.

Closing. This was likely fixed by the Qt version updates.
