Summary: Firefox/DHTML: Add autoscrolling to inputtext/edittext

Details:
Input text does not scroll properly in Firefox/dhtml. In IE and Safari
the user can scroll through the text with the mouse and insert text as
expected. In Firefox, text scrolls off the bottom of the window and only
the cursor keys can be used to see the missing text. The cause is
overflow:hidden that is applied to the <textarea> element. When the
scrollbars are not shown in Firefox it is difficult to move through the
text.
I added a new quirk, ff_autoscroll_textarea. The
LzInputTextSprite#__textEvent handler has 2 new behaviors when this
quirk is true. First, it will scroll the window when you click/drag the
mouse up and down to expose the hidden text. Second, if the cursor is
placed at the end of the text, hitting a carriage return will also
scroll the text (when you type another character).
This does not completely emulate what flash does or the behavior seen in
IE/dhtml, but it addresses the jira issue and also adds basic mouse
scrolling.
Tests:
Test case in jira report. Compare before/after behavior in FF/dhtml.
