Added Nuke Launcher! :)

This update finally adds the nuke launcher and nukes. :)

They are super-destructive, so be careful! (However, they are also a good source of some of the heavy radioactive isotopes due to their fallout)

Other things in this build:

• PERFORMANCE: optimized the highlight code for drawing lines with the Hammer and other tools, so it should run at normal speed now

• Added a rolling set of backups for the world header savefile - if you have an issue with the ship inventory disappearing (not sure what triggers this yet) there will be up to 5 rolling backups in the world directory you can restore to.

• AdjustedBALANCEreduced the Ruby cost for unlocking the turret pixel category to 16 (from 64)

• BALANCE: procgen now ensures at least one Cobaltite room in the lower layer of the limestone caves

• MISC: F2 to toggle Editor Mode now only works after entering the command [c]editor[/c] in the console

• AddedMISCadded a property to materials to be able to have unnecessary pixel types not appear in the Guide Tab (for technical variants of pixels so we don't see lots of pixels with the same name)
• FixedBUGFIXfixed some material rendering errors in the Guide Tab
• FixedBUGFIXfixed some incorrect localizations in German and Russian

• BUGFIX: Hydrogen Bromide Gas can now condense into a liquid

• BUGFIX: when clicking to replace something in the toolbox, we now do a check of whether the target slot contains an item that shouldn't go into the source slot (previously only checked one-way, and could get the save file into a corrupted state)

Thanks for checking out the game! We'll be launching very soon! :)
