Dual Wield plugin updated to v2.53

Updated the plugin to version 2.53 fixing the following bugs:

• Corrected an issue with the previous fix in v2.52, where the plugin would mistakenly forget all offhand weapons.
• Corrected an issue with the 'barehanded attack' parameter, where if it was set false, any dual wielding actor would swing their main hand weapon twice instead of swinging their offhand weapon.

The demo project has been updated to contain the newest version of the plugin.
