Bug#408984: CSS files

[Teemu Likonen]

retitle 408984 vim-runtime: Does not set 'omnifunc' for filetype "css"
thanks

Well, actually it's not only about *.css files. The 'omnifunc' should be 
set when 'filetype' is changed to some filetype which supports omni 
completion. So, just like the command "set ft=html" also sets 
omnifunc=htmlcomplete#CompleteTags the command "set ft=css" should set 
omnifunc=csscomplete#CompleteCSS.

Anyway, my previous message contains fix to this.
