#3 Wait for methods

[Stefan Roock]

In the current implementation the test execution waits
until the action in the script is executed by awt/swing.
If e.g. a button is clicked the test proceeds when the
click was done.

Sometimes (especially when threads are active) the test
has to wait for other actions like:
* a certain component becomes enabled (often the
clicked one)
* the mouse cursor returns from sleep state back to
normal state
