Linear Offset, OFF L

Hi,

I needed a way to use use the offset command OFF J and make linear moves (plunge straight down). I couldn't find a way to do this with what the AR4 v4.4 currently offers, so I implemented a OFF L command, which does what it says in the name: it offsets from a register position linearly. I didn't actually write anything new here, the command is just the OFF J and MOVE L commands mashed together.

If you want to use this yourself, using the AR4 Mk4 control software source, use this patch file to add it to your own version. Apply with git apply LinearOffset_AR4-v4.4patch.txt

Would be nice to see something like this implemented in the official version (though it's not out of the question there's a way to do this already and I'm being a massive fool :)). I can't be the only one who could make use of something like this. Thanks!
