typeText

This component allows you to have text from a textfile or
variable be typed onto the screen letter by letter.

The component has two parameters:
1) textToType : set this to the text you want to appear
2) textfile : set this to the path to a textfile containing text you want to appear

* the text in the textfile must begin with 'scrolltext=' and must not contain '%26'
* call the internal function 'loadText(textfile)' to load a new text file
* edit the textfield inside the component to change its size or
font, color, etc.
* you can use some flash-supported HTML tags in the textfield,
eg. 'BR' to break a line and 'A' to link
* change framespeed of movie to vary speed
