[WIP] Lots of improvements

[ndbroadbent]

Hello, I wanted to share a work-in-progress branch I've been using that has a lot of fixes and improvements.

Bug fixes

• Ignore click events when the mouse is being used to control the camera.
  • Fixed by checking the duration of mousedown => mouseup and ignoring drags over 200ms. (I did it this way so that tiny accidental movements don't prevent clicks, which was a problem with my initial implementation.)
• Fixed the default behavior for the hideLevelsMenu option - This should be 'yes' by default when it's missing from config
• Ignore clicks on level or zoom area buttons (with ev.stopPropagation()), so that they don't also toggle lights or gestures

Improvements

• Added initialLevel option to config, to only show one level and hide all others when the card loads. Very useful when working on a floorplan.
• Disable window.prompt popups by default in lovelace edit mode. These can be turned back on with: editModeNotifications: 'yes'
• Always log object IDs and camera information in the developer console
  • Always fire default actions, even in edit mode and when showing prompts. (I found it really confusing that my lights weren't turning on.)
• Added a level option for zoom_areas. When set, clicking on a zoom level will also show the specified level and hide other levels.

New Features

• Selection Mode: Set `selectionMode: "yes" to visually select multiple objects and show the list of IDs.
  • When selection mode is enabled, you can click any surface to turn the color blue and add the ID to a list of object IDs that are printed in the console.
  • I use this mode to select all the floors and walls that I want to click in order to turn on the ceiling lights in a room, and visually confirm that I haven't missed any.
  • This adds a new buttons bar to the bottom right of the screen where you can clear the selection, or enable/disable the selection mode.

Please let me know if you have any feedback! Sorry for the large PR, I thought it would be much easier if I could put all my commits in one branch for now, since it would take lots of time to split it up into separate PRs, and I'm still adding new things. I would be happy to remove or change any commits from this PR, just let me know!

Thanks for working on this awesome project!

Hello Nathan, I will not have full time to test but I like the enhancement and I trust you. Thanks for the effort. I have some ideas for a version 2.0 but as you have noticed I'm not good at JS coding, so some help is welcome.

Should I release it ? If you feel confident I do a 1.5.0 and add your comments. At the third succesfull pull, I add you as code owner

Thanks a lot! I am using it now and it seems quite stable, but I will continue working on it and might need to fix some issues. I might send another pull in the next few days, maybe it would make sense to do a new release sometime next week once I'm a bit more confident in these changes
