Dialog revamp and Events Manager organization

The Dialog Interface has been reworked. You now have more freedom when using the dialog tags. They now work without the need of spaces, so a single word can now have multiple tags within them.

The Dialog Tester behavior was added. It lets you test multiple dialog lines and change values at runtime, for easier testing. Specially useful when checking several text lines from multiple localization files.

The Time Count behavior now stores the time formatted as text in a separate key in its save global value, and has been internally revamped as well.

The Events Manager behavior's Event List attribute has been better organized, and events about actor positioning have been reworked. It should be now easier to find a particular event in the list. Also added a new, separate documentation file just for the Events List, for ease of reference.

Happy Stencyling!
