Can't connect rooms on mobile

[dfabulich]

In Chrome 81 for Android 10 and in Safari for iOS 13.4, there's no way to get the room connector circles to appear. They appear on hover, but mobile doesn't have hover.

When you tap on a room, you see the resize squares, but not the room connectors.

I can think of two ways to address this.

1. Clicking on an already selected room should toggle between "resize mode" and "room connector" mode.
2. Perhaps there should be a "connector" tool in the tool bar; when selected, all rooms would show connectors by default

@dfabulich -- those are great ideas. I'd suggest the "connector" path tool / line tool approach. It could be possible then in addition for multiple clicks on a room to switch between arrow, room tool, and path tool, but that could be extra interface on top of the basic explicit "I want to draw paths" feature.

I experimented with this a bit this morning. The connector dots are so small and close together that it's hard to tap the one you want unless you're so zoomed in that it's annoying to drag from the start room to the end room.

In issue #82, I suggest that clicking on a connector dot would behave like the shift-arrow shortcut. That would probably be a big help on mobile; you can zoom way in on a room and click on a connector to create a room in that direction.
