Version 2.65 minor bugfix

Good morning folks, and welcome to the last update post for the dual wield plugin for 2019!

I have uploaded a small fix that prevents a very specific crash in the plugin, following the release of version 2.62.

• Using an older (< 2.62) save game will no longer cause the equip scene to crash under some circumstances.

The problem is caused by one of those quirks of the way the save system works in RMMV. Using an older save created before the 2.62 update causes a value stored on all weapons after the update to remain undefined. Because the plugin was expecting that value to be present on all weapons, it was not first making a check to see if the value was present before trying to read info from it. As a result, older save files would cause the equip scene to crash.

The crash error has been corrected, but the locked wtypes feature added in v2.62 will not work at all until a new save file is started, but it should no longer crash the engine.
