VIM support for syntax hilighting simplates

Warning! We override the default syntax hilighting for .spt files, which are typically SNOBOL4

• fix vim hilighting with jekyll (yaml + markdown)

I don't know of anyone using this plugin yet. The workaround right now is to manually do :set filetype=python or :set filetype=html as needed. You can set a default for the .spt extension with this in your .vimrc:

au BufNewFile,BufRead *.spt setlocal filetype=python
