When installing multiple packages (or one package that requires others packages)
with different licenses the updatetool user is prompted with a single "License
agreement" window stating "You must read and accept this license before
proceeding" and concatenating the licenses in the text area.
Chances are that any license will fill up the viewport and thus additional
licenses will not be available. The use may think he's agreeing to a single license.
- change the text to say "... the license(s) below before..."
- force the user to scroll down to the bottom of the textarea before the
"Accept" button is enabled
