Electrical Age

This is a rollup release for various bugfixes / improvements(?) that made it into code but haven't been released.

Highlights:

• - The electrical tools (axe / pickaxe) now have treecapitation and area-mining modes. These are enabled by defaults; right-click to toggle.
• - The portable battery packs have been buffed accordingly. You may still need more than one for continuous mining.
• - The 200V machines are now significantly faster, but draw more power. This may give the 50V machines a niche further into the game. Be careful not to explode your base.
• - Creosote is now a valid fuel for the fuel heat furnace.
• - An improved flashlight with significantly more range has been added.
• - Various bugfixes to the PID and other chips.
• - The autominer now supports ores with multiple item drops.
• - Most/all icons have been swapped for more easily recognizable versions.
• - There is a new emergency lamp item, which can be powered off an internal battery.
• - There is a new 'scanner' item, which in principle duplicates the functionality of the vanilla comparator, but outputs an analog circuit signal instead of a 0-15 redstone value. It may or may not work.

Progress is continuing (somewhat faster) on the rewrite/port, now targeting 1.15.

No warranty included.
