[Vimoutliner] The easy way to add new VO file extensions

[Steve Litt]

Hi everyone,

Look what I have in my ~/.vim/ftdetect directory -- a file called 
my_vo_extensions.vim. Here are the contents:

augroup filetypedetect
  au! BufRead,BufNewFile *.emdl         setfiletype vo_base
  au! BufRead,BufNewFile *.ebdl         setfiletype vo_base
  au! BufRead,BufNewFile *.pho          setfiletype vo_base
  au! BufRead,BufNewFile *.rl           setfiletype vo_base
augroup END

So on my computer, Easy Menu Definition Language (.emdl) files, EBDL flies 
(.ebdl), Phone number lists (.pho) and Rapid Learning files (.rl) all come up 
as outlines in Vim. Note that there's nothing special about the filename 
my_vo_extensions.vim -- as long as the file's in the ~/.vim/ftdetect 
directory, ends with .vim, and contains the above contents, it will work.

In order to have your file extensions survives VO upgrades, you can make it 
symbolic link to a file in a backed up data directory.
