Automatic Reading List Creation

[majora2007]

Investigate auto creation of Reading Lists for the server (promoted?) that use the following information. (Note: This requires comicInfo.xml parsing for each file, which may eat up more memory and time) (Note: We can add a flag on the MangaFile if it has ComicInfo or not)

The AlternateSeries or StoryArc tags will be used to create a read list with that name, or add the book to an existing read list with that name.

If the AlternateNumber or StoryArcNumber tags are set, it will be used to position the book in the read list.

We can use this in epubs and comicinfo.xml

In addition, look into support cbl files for reading list creation

The foundational work has been done in v0.4.7. The rest of this only makes sense when basic metadata is supported. Moving this story with that work.
