Command to post Pixiv stickers

[logan-m]

A command for posting Pixiv stickers would be nice and potentially useful. This could be done with 37 separate learned commands, but that would be a bit annoying.

The command should be something like !!sticker (feel free to change to whatever you like), and should have a numeric argument indicating which sticker is to be posted. If the number is one of the valid stickers, it should post that sticker; otherwise post an error message of some kind.

As for a description, I suggest "/sticker num Posts a Pixiv Sticker. num is the numeric indicator of the sticker, in the range 101-109, 201-209, 301-309, or 401-410. To check what a particular number is, go to http://source.pixiv.net/common/images/stamp/stamps/###.jpg".

For convenience, I've uploaded these to i.stack.imgur at 140x140 pixels (which seems like a reasonable size for chat). Here they are:
