Feature request: Add the ability to scroll text

[teeedubb]

Hi,

Currently it seems as though there is no easy and reliable way to scroll text in AM, with the best method I have found being to rigid to work reliably for all lengths of text. With that method the size of the text box is static and defined in the skin, so long blocks of text are cut short and short blocks of text take a long time to cycle, leaving a blank area where the text would be. Also to reset the scroll you need to chose do have it done on either platform change or rom change, so after moving the cursor sometimes the text has already begun scrolling.

This would benefit many aspects of displaying text metadata and allow skins to have more space for other elements while still displaying the same amount of information.
