Add verbose script action texts to script actions list

[JoyfulShush]

Adds handling of most script action types that are handled via the script parameter value, showing the appropriate values on the script actions list.

Scripts actions will now show dynamic text, as following:

• Script actions with a numeric value (waypoint number, cells, etc.) retain their number. e.g. (10).
• Script actions with preset options now show the selected preset option text. e.g. (Keep Transports, Lose Units)
• Script actions with a certain handled type, such as local variables, houses, units/structures, animations etc. will now show the appropriate text based on the type. e.g. (GDI), (Game started), (Power Plant - Least threat), etc.
• Script actions that accept no values (typically shows "Use 0" on the parameter) will now simply show the script action's name, without any additional information. For example: #3 - Deploy.

See below example of script actions in action:

Additionally, removes unhandled, unused types for TeamType for Change Team and ScriptType for Change Script. They are both unhandled correctly by WAE, and it serves no real purpose; if it will ever be implemented correctly, can be expanded to support the types.

I think it'd be useful to still show the number even when showing descriptions. For example, with locals, it's useful to see which number it is, so instead of

Set Local (Waves remaining)

You'd have

Set Local (1 Waves remaining)

or

Set Local (1 - Waves remaining).

Excellent idea. Done. I went with the Set Local (1 - Waves remaining) variant.
