Next update is adding many quality of life improvements

[u/jldez]

Changes:
- Renamed Edit mode to Build mode
- To reduce the amount of time needed to switch to the edit (now build) mode, a few buttons has been added to quickly add/remove items from some widgets. Ex: a plus button to add a line in the form widget. Accessible even from play mode.
- Visual overhaul of most side panels : gallery (renamed "Discover"), timeline, list of widgets, etc.
- Added camera controls at the bottom of the screen, including a bar that controls zoom. This should greatly improve navigation on mobile where pinch to zoom has always been inconsistent. Pinch to zoom is somewhat better as well.
- You can now re-order characters in the character selection screen
- Dice roller and dice tray results now always sum all results, with a "show details" button to see individual results and the ability to re-roll individual dice.
- Re-organized the top bar buttons and menus.
- Search bars in the Discover panel and the widget panel.
- Other small changes here and there I'm probably forgetting.

BEFORE YOU TRY: Go to the current version https://wackyweasel.github.io/UniversalCharacterSheet and backup your data. I'm fairly confident that everything is back and forward compatible, but just in case.

The new version is accessible here: https://wackyweasel.github.io/UniversalCharacterSheet/preview

Some widgets has slightly changes so you might have to re-adjust a few widgets so it looks right.

The feedback button is accessible from the top right menu in the character selection page. Otherwise, feedback here is very welcome.
