additional scripts for emailing bugreports after capture

First script calls dumpsys to generate the bugreport, second
script launches a cmd line tool that queries account manager
for possible accounts to set as "to:" field and launches an
intent to mail the bugreport out

This is done in 2 steps because it's more convenient to look
up account for emailing with a framework context, but to make
sure bugreport is captured, using dumpsys from shell script
is more reliable in case Dalvik VM crashes.
