Some UI improvements

[Mestre Lion]

I've posted a few "feature" branches that I would like feedback/testing from you guys:

https://github.com/singularity/singularity/tree/feature/show_difficulty

Shows the current difficulty in the game screen. Currently there are no means to know what difficulty a loaded game is. The best place for it should be right below the MENU button, but for low resolutions the RESEARCH / TASKS button gets in the way (specially for Portuguese and Spanish), so I tossed it above the FINANCE button.

Suggestions and patches to place it somewhere else are welcome.


https://github.com/singularity/singularity/tree/feature/overflow

Puts a limit on money (3.14qu), so no more overflow bug reports. Closes https://code.google.com/p/endgame-singularity/issues/detail?id=110 and possibly others. Also changes money display to 2 decimal places instead of 3. Its more sane and distinguishable (many, including me, thought 800.000 was 800 thousand. 800.00 makes it clear).

Suggestions on the best limit are welcome.


https://github.com/singularity/singularity/tree/feature/show_time_remain_base

Show the time for completion of base being built on the location screen (the list of bases in a location). Closes https://code.google.com/p/endgame-singularity/issues/detail?id=86 and possibly others. Current format is "Building (xx%): xx days". Also makes text input of base names and cpu numbers a little larger.

Suggestions on what to show are welcome. Be aware that remaining time is not accurate: base may have completed its required build time, but still be short on money (or cpu). The percentage is accurate (shows the % of the /least/ completed resource. Will this confuse users?

Cheers!
