feat(web-console): Add URL deep-linking for UI panels

[insmac]

Add URL deep-linking for the UI panels:

?topPanel=p1 (default: p1 - tables - this is future-proofing, as there will be more in near future)
?bottomPanel=p0|p1|p2 (default: p0)
?sidebar=p1|p2 (default: none)

EDIT: Closes #245

We could assign panels and their states integer IDs, this way we can keep backward compatibility even if UI changes. Dependency on panel human readable names is not ideal.

if you have less that 3 tables to have zero-state panel visible, go to this URL: http://localhost:9999/?bottomPanel=result execute a query and observe query result not being displayed
