Allow menu during events - for Visual Novels

[Taylor]

In truth, I don't have a plan to release this system public on the basis I don't trust it to be stable. However I am showing it because I would like any pointers as to improvements on how to better handle what I have.

This script allows the menu to be opened during events. Due to the way events are handled in XP, this isn't quite straight-forward. This script backs up events to where they were after the menu was opened (important for re-reading messages), and makes sure to skip the "mid-command" lines RMXP seems to have (things like Show Choice are actually interpreted in multiple lines, not as a single command).

The last point is specifically something I want to watch out for. I have an array there of every command index that leads to an actual command, but I cannot say for certain that this is the most apt way to handle it?

Oh brill, that's handy, very handy. Thanks for sharing!

Minor update to avoid an error if you open the menu before any events happened. ... which wouldn't show up in a demo I'd imagine, but better safe than sorry 'case it affected other things.
