Implement Filtering by Location (58)

Save and Load Topology View (46)
A Topology Viewer page (`plugins/nextbox-ui/topology/`) now allows you to save a current layout to the database.
A saved topology is a "snapshot" of the topology state on the screen with all associated attributes.
A saved topology can then be loaded from the Topology Viewer page. Overall device layout and their relative coordinates will be preserved. General plugin Hide/Display controls are also preserved on the view save/load.
Device and link changes taken between save and load actions are not currently considered. Load Saved View shows a topology state in the past as is.
Tracking changes is a matter of further development.

Device name in a node tooltip is now a link to NetBox DCIM device page.
Node tooltip appears on single left mouse button click on the topology node.
Click on the device name to jump to this device page. It will be opened in a new tab.
