v0.0.0.57 - Health & Maintenance

Items,  Structures & Droids now have health. Although currently only solar panels take damage overtime (from micrometeoroids), which reduces power output. Droids will now repair the solar panels when moderate damage is reached. Other changes:- 

• Few little cosmetic fixes and tidy ups (info window).
• Droids now get closest build job.
• Lot of changes as everything now has health/efficiency, ready for next additions.

Next things to do:-

• Everything needs to have the chance of damage (either from outside micrometeoroids or general wear and tear) & therefore need to be added into droid repair checks.
• Droid maintenance should repair droids if they become damaged.
• Droid custom priorities of build/haul/repair.
• A 'repair now' option for manual override.
• Want to add some gfx effects to items that are damaged, so they can be spotted easily.

Will also need a bit of balancing as quite a few additions. I may be able get a small update out before xmas, with improved balancing and some of the above items.
