Add hidden "ArrayBuffer" option (for ZIP)

[yuri-kiss]

This adds a hidden arrayBuffer option to the menu which can be enabled by setting "_showArrayBufferOption" to true. (its meant for other extensions to do it)

I am making a buffer extension and wanna PR it, but the current method to add support is 6KB of patch code so I wanted to do it internally.

i expected this to be in the same pr as the buffer extension itself
