Utility ButtonMaster Beta v03-21.1-beta

- You can now clear icons/test colors with a right click
- Iconic buttons (see below)
- Icon buttons now use Selectables to behave more like normal buttons
- All spell Icons now available.

- Fixed an issue where if you used a previous beta version and it brought over a Label as a number you could get crashes.

- ButtonMaster can now be locked with the Lock Icon in the top left.
- You can now select Icons from the spell Icon list to go on buttons along with text.

- Fixed a legacy bug where labels could be numbers
- This could cause sorting to crash
- All Labels are now strings.

- Fixed a minor issue that cause 1 extra row to show if your last defined button ended as the last button in the previous row.

- Fixed historical bugs:
- The way that buttons per row were calculated was wrong using a hard-coded value of 5 instead of the actual padding value
- Buttons will no longer go off into invisible width space

- New feature
- Buttons will be displayed up to the end of a row of the last defined button.
- This means that if you define button #88 we will render up to at least button 88 and possibly past it to get to the end of the row that button 88 renders on.

Requires RG Build 240120.2184
