Shared interface for electrical interfaces

[Guvante]

• Added a Turbine.lua to control turbines whose power is controlled dynamically
• Migrated most of the Aerial.lua code that made sense to share here
• I believe I successfully duplicated the logic required for the basic wind turbine to work
• Still a ton of work to be done to migrate tides which haven't been started
• Still more work to migrate other wind turbines since their prototypes are un-altered
• 99% certain this will all break due to not properly handling the blanks but haven't looked into that properly yet
• Need to update GUI when you select one to duplicate the current preview of how effective your wind turbines are
• Untested and likely completely broken still but figured I would get insight into whether this was a good direction since I needed to take a break for a couple days

Resolves pyanodon/pybugreports#499 (well once I finish the work)

[Guvante]

To reiterate this is totally busted but the shape of what I am doing is done (well still need to figure out GUI but otherwise I think the skeleton is good if untested)

I'm sorry you had to deal with my aerial code

[oorzkws]

By the way, have you seen real-world issues with performance that pyanodon/pybugreports#499 suggests?

[Guvante]

Nope I was just going through issues and found one that seemed... "Easy" (?) something that didn't involve balance let's say.
