Unmaintained [ITM] Chevereto Integration 2.2.3.1

Fixed an issue in the helper template that hide all upload buttons.

I've made an update to prevent a little bit more issues with the Froala Editor in XenForo 2.2.x

• different positions for the upload button
• choose if you disabled the XF attachment permissions

Feel free to test and comment any issues

This is just a release for XenForo 2.2+ to fix issues with the new Froala Editor.
