Removed default values from renderer configs + formatting

@UniversalMediaServer/developers I'm making a pull request for this because there have been a huge amount of changes in here and maybe I missed something or made a mistake that you guys will see.
There should ideally be no functional changes in here, just formatting and removing default values.

There are a few reasons I've been wanting to do this: it makes it easier to compare renderer configs, eliminates outdated comments by keeping all of the generic (non-renderer specific) ones in PS3.conf, and hopefully having smaller renderer configs will make them seem a little less daunting to users looking to make their own.

If you guys have any suggestions for formatting of the renderer configs please feel free to make them.
@SubJunk Transcoding of tiff images fails with this TV. It results in infinity loading.

By adding tiff to the supported lines, the TV recognize tiff images as an unsupported format (marked by a cross) so that it can't be played faulty. That is the reason I added tiff to the supported lines.

This is not needed with gif and png image files.
These files are already marked by a cross and thus unable to play.

However transcode works for .NEF raw image files (NEF Codec) with dcrawMS.

So there is something wrong with the transcode of most image files with this renderer.
 
I guess, until this bug is solved it would be better to have this tiff supported line in this renderer config.
