Enable MAME recording/playback in VPinMAME

[droscoe]

MAME, which is the base that PinMAME and VPinMAME is built upon has an inherent capability to record inputs and play them back. This is a useful feature for testing and debugging issues with ROMs, as it saves the developer from having to reliably reproduce a problem multiple times. A single recorded instance of a problem is all that is needed, and can be iterated upon until the problem is resolved.

The .NET framework built around VPinMAME does not support this feature in its options list. Additionally, it does not have the necessary code to pass it to the core MAME engine, making it impossible to enable via hard-coding. I'm requesting that the ability to record and playback ROM inputs be added to VPinMAME
