JSify Ass Fitting Event and fix VCheck in previous events

VCheck returns a string that should be pushed to t, so I added t.push to events that were missing it.

@svornost This time I got stuck on drawEventArt(). The event first draws slave without clothes, then you have the option to help her don her clothes. When clicking this option the artwork should update to show her with clothes. Using drawEventArt twice results in two images. Is there an easy way replace first clothesMode with a second one (or original clothes)?
