* Change the Tables.tpl template so that the back link only shows when the photo
list is shown.
* Increase version number to 0.9.1 in prep for next release. Note: the major
change since Album 0.9.0 are the changes of using class variables instead of
passing them by reference to fix the PHP4 only bug: [#1510] Links in Album 0.9.0
are sometimes blank
* Remove the uneeded allpictures parameter from SetupAlbumContent() and just do
the smarty assign in that method.
* Don't pass current_album by reference anymore. Instead pass the album_index
and use the 'albums' class variable.
* Move all methods in the AlbumFrontEnd class to the Album class so that Albums
can be stored and shared in an 'albums' class variable.
* Update default template and stylesheet so that the Albums in the Album list
are floated left like they used to be.
* Use a class variable for storing array of links instead of passing by
reference.
* Fix typo. Thanks reneh
