Vamooses SlipStream

### Look
- On WoW: Forever, pick how Slipstream looks in Settings: Classic matches the
  game's own windows, in Forever's bronze and gold; Modern keeps Slipstream's
  own dark, rounded look. The main window, the step list and its map, the map
  window, its key and the pin callouts all change as soon as you pick
- The cog beside the map button on the main window switches the look, and
  opens Slipstream's Settings
- The small "//" beside long steps in the step list is gone

### Follow it
- Getting near a step's end is enough to tick it off. How near is up to you:
  "Step reached within" in Settings, 30 to 100 yards (50 by default)
- Took a shortcut? The route catches up to the furthest step you've reached,
  ticking off everything before it
- Click any step in the step list to go to it, back or ahead. Clicking
  Arrive finishes the trip

### Go to coordinates
- Paste coordinates into the search box and they come up as a place to go:
  Wowhead's "/way #1438 55.9 89.3 Rut'theran Village" just as the guide gives
  it, "55.9 89.3" for the zone you're in, or "Stormwind City 62.3 71.1" for any
  zone by name
- /vss way followed by the same takes you straight to the route
- Your map pin sits at the top of the list when the search box is empty.
  Click a map pin a friend links in chat and it's yours, ready to go
- With Slipstream open, clicking a map pin link in chat puts it straight into
  the search box
- Once you set off, the place gets a pin of its own (named, if you gave it a
  name) so you can find it again in the map window and the search. Going back
  to a place you've pinned uses the pin you already have
