Ideas for Drox 2

[Bluddy]

* It would be nice to be able to press enter on screens with just one button, such as after trading and getting a reply from a race and an 'ok' button.
* Spies are currently a little confusing. I built a few (50 spying), used an action (-30), and failed and immediately lost all those spies without being told about it. If my spies are caught, I should be notified by message about it.
* Also, I guess spy points (which are separate from spying) are per race rather than per planet? If so, it makes it really hard to spy on large races, because you'll fail some of the time, thus alerting the whole race. I think it makes more sense to make them per planet.
* There should also be a way to tell my spies to lay low so they don't get caught.
* Honestly I'm a little confused about how the system works now that I realize that there are 2 numbers for spying (one for the number of spies per planet, and one for status of spying per race). Some clarification would help. Using a planet action should not cause my spies to get caught, even if they fail, unless they are specifically caught... Yeah, it's confusing.
