Fixes and stuff

- Added "publish book" button to the books column
- add box for 'settings' to books, currently unused
- using GMT for book modified dates
- access picture alignment, but turned OFF since it looks bad in templates.
- Fixed bug where a blank x, height, or width was inserted when there was no value.
Let the templates do the work

- Removed height/width/x from book.xml output so template can determine those values. That way, pictures will fit the template, and we don't need the blog pix to be sized beforehand.
- Modified date can't be NOW, since all books would always need updating!
- Added "Ignore Me" code that so something beginning with ### will not appear on the page, usually a title. Might not work with text, not sure!
- fixed functions for getting which book a post is.
