Chemical Option v0.34.2.7

Now depends on Solar UI mod. I hesitated to make a library mod but after realizing how many mods I want to make that will require a UI library of some sort, figured it would be best to just get started on that now.

Also, added new missile readouts and engine readouts!

Also, mod ID changed from vet.solar.chemical to Solar.ChemicalOption... sorry 7ep3s. Not sure what difficulties that is going to cause but we'll find out together!

Chemical Option v0.34.2.4

Development build using some borrowed code from George's NOTT.

This will most likely be re-written from scratch but I figured I'd upload it for the two people who want a fuel burner replacement until I release the rewrite.
