Add "Planet Info" button in controls

[evangipson]

I can probably use the "Location" button for this.

This button will display some information about the planet you are on (this can be done easily by augmenting the objects inside of the locations array). I'll probably add a few properties, like:

• Min Temp
• Max Temp
• Planet Type
  • https://en.wikipedia.org/wiki/Planets_in_science_fiction#Planet_types
• Native Resource (I plan on using this for "resource discovery" later on - the planet will discover more of it's native resource only - making the price of that resource super cheap even though it's worth a lot)
  • This ties in directly with issue https://github.com/evangipson/microstocks/issues/38.
