Do not override bookmark on update

[https://wiki.navit-project.org/index.php/user:haandoo]

Everytime I update SVN from Android version my bookmarks are gone. That should not happen.

Actually I found on the wiki that: "At this present time, the bookmarks.txt file can be found in the following location:

/data/data/org.navit-project.navit/home/bookmark.txt You will need root access on your device to be able to access this file."

Why is it necessary to be root to access the bookmarks?

This is indeed something which needs changing - see #750, and I think there's another similar ticket floating around somewhere....

From my personal experience on an SGS2, this no longer happens.

If someone finds that this starts up again, please re-open this ticket!
