Android needs 64 bit builds

[andrew at midwestcoastmedia.com]

This was originally mentioned in a message at the end of January, but  
that thread never went anywhere. I submitted an updated app to Google  
Play today and noticed the warning message myself for the first time.  
It seems we have a few more months to prepare for this, but can't  
recall seeing any mention of this on the LiveCode roadmap.
