Jms Multisite for Joomla version 1.3.81 All Editions

• Fix save of the settings when testing the JPATH_ROOT
• Fix the "InstallComponent_j16" under Joomla 4.x to fix column list that changed in #__extensions
• Fix some Javascript error under J4.0 in JMS / Tools and JMS / Maintenance
• Replace call to Mootools or JQuery by native Javascript
• Add PHP 8 compatibility.

Bundled with Patches definition 1.3.73

• Fix a patch under Joomla 4.0 to "temporary" remove the JMS InstallerOverwrite to allow re-installing an extension inside a slave site without any verification.
  The InstallerOverwrite is complex under J4.x because when JMS is started, Joomla is not initialized yet and under J4.x, the Installer require that Joomla application is initialized.
  So we decided to disable this feature in JMS while we are searching for another solution to continue providing such functionality under Joomla 4.x
