Demo version with all main package data.

I have just realised at this point in time that we are about to go free, but as long as we are declaring it free, we should have included all the data from the main package in the Demo version.
I'm sorry that our staff are a bunch of idiots.
Maybe now the Demo version has the Mainpackage data in it.　Please contact me if you find any problems.

(Also, the update of ChapterEX2-4 will probably take at least a few more days.　Sorry for the delay)
