Fixing the Horrid UI

[dmm]

Most-needed UI fixes, IMHO, in order of importance:

#1: show what a planet is building in the info that first comes up when you click on a planet. Instead of "click, q, Esc" or "click, right-click, Esc" you should just have "click."

#2: a hotkey for facilities.

#3: a hotkey for cargo (planets or ships)

[Actually, I much prefer SEIV's 2D top-down UI (although I do like SEV's hexagon grid better than SEIV's square grid). I'd make THAT my #1, except I know that ain't gonna happen.]
