(svn r22651) [1.1] -Backport from trunk:

- Fix: When closing an AI company the local player cheated to, we need to cheat him to another company [FS#4654] (r22624, r22623)
- Fix: When closing down companies their shares in other companies must be sold even if share trading is disabled at that point of time (r22622)
- Fix: When asking the user to confirm an unsafe unpausing, there is no need to execute a command if 'no' is choosed. This also prevents crashing when clicking unpause while the confirm window is shown (r22621)
- Fix: Enforce refit orders to be 'always go to depot' orders; service-only and stop-in-depot orders make no sense with refitting [FS#4651] (r22620)
- Fix: Consider the size of the vehicle sprite for the lineheight in the company GUI. This also makes the widget containing the sprite not skip drawing it, if the bounds of the widget are outside of the drawing area though the sprite actually needs drawing [FS#4662] (r22619)
