Fix multiple issues with the confirm plugin 

- Only allow one confirmation to be open at once. This avoids situations where
  pressing "s" would open another confirmation instead of the settings screen
  (e.g. in the trade screen), and allows all confirmations to be implemented
  without priorities specified.
- Fix #821: close any active confirmations when they are disabled.
- Some misc. cleanup, C++11 features
- Fixed a memory leak
