Quick Skin

# Update - 2.4.0

## News
* **Configuration panel**
> New button added, which opens a submenu for settings. For now, there is only the following option, but I have big plans, so it was worth it. 

* **Setting: Disable transparency in skins**
> You can now disable skin transparency at both the client and server levels directly from the new configuration panel without having to restart the server to apply the settings.
> -# *Thx @earlylover  for the idea!*

## Upgrades
* **Window closes when you click outside of it.**
> The windows that open when deleting/renaming a skin and when opening the mod settings now close if you click outside for greater fluidity.
* **Change the appearance of the Delete button.**
> I don't know why it always clicked cancel, so now that doesn't happen anymore and it's cooler.
* **Setting: Stylish buttons**
> I've added an option to change the appearance of the buttons, but I'm not entirely convinced, so I'll leave it as optional.

## Fixes
* **Fixed issue with Scale GUI**
> When you exited the skins menu, the GUI Scale was automatically modified, causing you to lose your own configuration.
> -# *Thx @brosquito  for reporting the issue!*
* **The custom window for deleting a cape now appears.**
> It worked correctly for deleting a skin, but when deleting a layer, the low version kept appearing.
* **Fixed random crash on small resolutions**
* **Sometimes with transparent textures, the arm looked opaque in first person.**
> The texture of the arm was filled with black pixels for some reason, but it should be fixed now.
