Major/minor grid lines in the room editor

[DragoniteSpam]

Is your feature request related to a problem?

Sometimes when placing things in the room editor (especially tiles) it would be nice to be able to snap them to a small grid, but still be able to see a larger grid to orient yourself.

Describe the solution you'd like

A lot of image editors have something like this.

The major/minor grid could be differentiated with different colored lines, lines of different thickness, dotted lines, or all three at once.

Describe alternatives you've considered

Right now I usually use the other tiles and other stuff in the room to keep track of where I am but that only works if the rest of the room is already filled in.
