New option for the floor board add-on

The floor boards add-on now has options to shift the origin of the pattern. This might come in handy when aligning pattern with different features of your architecture.

An example is shown below (the offset options are outlined in red, the pattern on the right has its x-origin moved a bit)

Note that like many options of the floor board generator there is a sensible soft limit on the value. Any soft limit can be overridden id becessary by entering a value by hand.

Code availability

The new version is available on GitHub.
