Adds an info button to GSV window in Explore, Validate, and Gallery

[misaugstad]

Resolves #340

Adds an info button to the GSV window in Explore, Validate, and Gallery. It shows lat/lng, pano_id, street_edge_id, region_id, and label_id. The label_id is only shown on Validate and Gallery because you aren't focused on a single label on Explore. There is also a "View in GSV" button that opens GSV in a separate tab, pointing the location you are facing in our tool. There is also a button to copy the text of the table to your clipboard; the text looks like this (an example from the Validate screenshot below):

Latitude: 40.02551965977139°
Longitude: -82.9848103319417°
Panorama ID: wVC_rq_SQxB4FlisFJ2LnA
Street ID: 24068
Region ID: 176
Label ID: 11765

I've also added this data into LabelMap, but I just put it in the table with the reset of the data so that we didn't have two separate tables. As @jonfroehlich suggested, we should have a drop down "details" section that most of this stuff goes in.

Just some "After" screenshots!
