[2019] Please fix this shit

You're unable to build that close to the wind generator.

Most if not all of the placement error messages are generic, we definitely need to do a better job at this.

Few reasons really:

• Prevent players from spamming down lots of Wind generators within close proximity and generating a ton of power.
• Prevent players using Wind generators as a defensive structure, like an extra layer of honeycomb.
• Sense of realism as not to block wind flow.
