Overview

NOTE: NOT USED. CONSERVATED DUE TO THE USELESS WAY OF NAMED MIGRATIONS IF PLUGIN WILL BE USED WITH RAILS (I suspect it will be common case scenario, because it’s not enough to create bots, it will be very often coupled with Rails for: admin, analytics, bot + websites stack, with registration in both places, etc)

Will not spend more time on this feature, if someone still wants to utilize named migrations here - you are welcome, please fire up a PR, we will look into it

Thanks to the craftsmanship in Redmine repository I was able to learn how it creates named migration versions. And now we can create our own strategy alike
