Still User Warning

Given the comments in #291587: User Warning as well as the update statements added in 5.x-0.2 and 5.x-0.3, my guess is that the preferred approach is to change the acted_upon column so that it is an int which defaults to null, rather than a not null int column. It looks like this approach was added to the _update functions, but not to the _install function, meaning that if you had started with 5.x-0.1 and upgraded up to 5.x-0.6, the code would work for you fine, but if you had installed 5.x-0.6 from scratch, then you'd get the error message.

The attached patch fixes the install file to use the approach found in the 5.x-0.3 update function. You will have to uninstall node_invite and then reinstall it to get it to work. That will wipe out your node_invite data, so if you have some node invitation data you care about, just issue this command to mysql instead of uninstalling node_invite:

ALTER TABLE node_invites CHANGE acted_upon acted_upon INT(11) UNSIGNED DEFAULT NULL

Whoops, forgot to update the status. I've tested this approach and it prevents the error message.

I've just applied this patch to the 5.x branch. Not too many people are using it anymore but thought it would be good to anyhow. Thanks for the patch @shaisachs!
