Subject: [PATCH] Parse out mediamarkers from all files

This commit updates the logic in
generateChaptersFromOverdriveMediaMarkers to create a single array of
objects that holds all of the clean MediaMarker data. it still needs to
be conveted to the NewChapters format.

I should also rename this function to "cleanChaptersFromOMM", but I"ll
do that later
