Add separate zoom wrapper layers for all video modes

Browse Source 
- Added live-video-wrapper around webcam-player
- Added timelapse-wrapper inside timelapse-viewer
- Added daily-video-wrapper inside daily-video-player
- Zoom now applies to wrapper divs, not video elements directly
- Pan works by dragging inside video container when zoomed
- Double-click to reset zoom
- Cursor changes to grab when zoomed > 1x
- Touch support for mobile pan
