animals user expansion from BBG user rillaith (#148)

* animals user expansion from BBG user rillaith
* Added fan attribute to animals set
* animals.png - This is not the best image.  But it is the best I could get from the original files. I *think* it is 3 penguins.
* updated main.py for fan based expansions
This includes two items:
1) adds --fan for specifying fan expansions to include
2) adds wild cards in specifying both --expansion as well as --fan.  This also fixes issue #149
* Updated all language files for animals
* Normalize all line endings and add gitattributes file to make git do so in the future
* print the possible expansions when non-matching ones are provided
* Allow for no official expansions to be included
Kept the default behavior.  Not specifying '--expansions' will have the same outcome as '--expansions *' (i.e., will print all of them.)
Specifying '--expansions  ' (without any named expansions) or '--expansions none ' will result in no cards from any Official expansion.

For Fan expansions, the absence of '--fan', '--fan   ' (without any named fan expansion), and '--fan none ' will all prevent any Fan expansions from printing.
* Cleaned up expansion/fan lists
