Merge branch 'feature/album_metadata' of https://github.com/redswitchio/ezstream into redswitchio-feature/album_metadata

Fixed the copypasta mistake of using the PLACEHOLDER_ARTIST value in the PLACEHOLDER_ALBUM conditional.

Reverted the comments to the orignal format and updated the documentation in doc/ezstream.1.in.in to include the album field.

Bump build version to "almost 1.0".
