Update of the README.md for Alpha 3

[televisionia]

Nothing big, just did some easy work for you.

• Made it so that it says now 4 players can support the script
• Made sure to mention battles are not supported yet
• Mentioned that trades are now possible

maybe add a hint for future support for all gen 3 games as well, so that this is also answered. (see #15 at issues) :)

@SWHSmash This is already mentioned in the original description, and hasn't been removed in the new commits, but I think you do have somewhat of a point, it should be made a bit more clearer. Will change!

I know that, but some people still ask for it. :P Okay :)

@SWHSmash If you want to get the attention of the repository author try submitting a review to the pull request

[televisionia]

The creator just changed the description, well, I don't think he noticed there was a pull request here either, so I'm going to close this as it is now not needed anymore.

[televisionia]

Closed because the description on the main repository changed, making the entire point of this pull request outdated.
