Change-Id: I291ed600428efb2d8ddabacd3f81d4295b2d1a38
update information dialog at welcome screen

people expect that their devices start flying once they install
the app and rant if their device is not rooted and the app wont start

then there are another people who rooted their device but are running
a stock kernel or a kernel with very limited features and then rant again
if their, for example Galaxy S3 (i9300) does not support "Knock On"

lets tell them that they need a custom kernel, this wont prevent ranting
at all but at least give them more information to cool down
