Theme ice is interpreted as "x-conference/x-cooltalk"

Sprockets::ContentTypeMismatch
jquery-tablesorter/theme.ice is 'x-conference/x-cooltalk', not 'text/css'

Hi @mirelon,

sorry, didn't find time to look into this before. Yes, you're right, I get the same error when using the ice theme.
I could solve this issue by adding '.css' in the application.css instead of only 'theme.ice'

*= require jquery-tablesorter/theme.ice.css

For me this looks like a sprockets-bug, but I'll update the Readme according to this and close this issue afterwards.
Btw, I think other projects ran into the same issue:
uxsolutions/bootstrap-datepicker#345

Cheers!
