fix my name in ChangeLog
check isInstallRunning then only check free memory

if isInstallRunning is set then no need to check free memory available in
install path.
disable "View Install Log" on menu if install.log does not exist
when deleting everything, also delete the install log
fix detection of loopback mount failure in install process

Oops, stupid syntax error my part.
run InstallService in foreground and show permanent notification

Running a Service in the foreground makes it much less likely that it will
be killed if memory runs low.  Foreground Services must show a Notification
while running, so this includes a basic notification.
