Main: Can take screenshot when no ROM loaded

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open Bizhawk, but do not load a ROM.
2a. Open the File => Screenshot submenu and/or:
2b. Press F12 (or whatever key you've assigned to taking a screenshot).

What is the expected output? What do you see instead?
The "Screenshot" menu item is disabled, but "Screenshot as", "Screenshot -> 
Clipboard", "Make Animated GIF" and "Make Animated GIF as" are enabled. They 
should be all disabled (or enabled, please be consistent).

Furthermore, I can bypass the disabled "Screenshot" menu item by using the 
relevant accelerator (F12). The PNG is written to disk.

What version of the product are you using? On what operating system?
r2164
