Zoo Empire by Enlight Software - English retail v1.2 patch

This patch fixes the following:

- Upon clicking the cash transfer menu's increase/decrease buttons, the amount
changed will now be in $5000 instead of $1000 intervals.

- The volume of the train and boat sound effects have been tuned down.

- The game will no longer crash if you mouse-over a visitor fence (this was due
to a bug that upon mousing over the fence, it would turn into an artificial
animal and crash).

- If you assign a zookeeper to feed an animal (or any other task), the
zookeeper (or other staff) will perform the task immediately. The hungry
animals will also start eating right after their current activity. This
addresses the "my animals died of hunger despite having zookeepers to feed
them" bug.

- The animal drinking AI has been improved so that they will drink water when
they are thirsty.
