Add Japanese (Windows) detection and minor extra support for Beavis and Butt-Head in Virtual Stupidity

[HeroponRikiBestest]

The Japanese Windows version works more or less properly in ScummVM as is; the only changes made to the 4 file types that ScummVM requires is that the sound .aif files were replaced with Japanese-dubbed lines, the video .avi files present in the english release had their audio streams replaced with Japanese-dubbed audio (video streams appear to be identical data-wise), and two new video .avi files were added, LOGO.AVI, which plays an additional logo sequence before the game starts, and VIDEO004+.AVI, which (presumably, I have not finished the game) displays the Japanese credits after the English credits from video004.avi have finished playing. All .000 files and .vnm files have the same hashes as their English version counterparts.

TL;DR

• As is, the Japanese Windows version already plays correctly in ScummVM.
• The only thing that needs to be added to "fully" support the Japanese Windows version in terms of gameplay is playing the LOGO.AVI and VIDEO004+.AVI files in the relevant spots.
• The Japanese Windows version needs to have proper detection added (atm it's just detected as the English version), which could likely be done easily by checking for the presence of VIDEO004+.AVI (or LOGO.AVI).
