Added comments to XML file.
For my use later.

Also added <CheckBoxPreference>
Added a few preferences to XML again.
Will probably get changed.
Added Filetag & Audio File Lifespan.
Audio File Lifespan is set to be a <ListPreference>... Might need to change this..

Also might need to add more to XML in these areas.
Removed some garbage. Currently, these are not integrated w/ anything. Also, when running on emulator, 6 settings boxes show up, but no text.
