add snipmate settings

[joaomarcos96]

There's this annoying message whenever I start vim:

$ vim ~/.zshrc
The legacy SnipMate parser is deprecated. Please see :h SnipMate-deprecate.
Press ENTER or type command to continue

This is because SnipMate's legacy version, as stated in :h SnipMate-deprecate:

The legacy parser, version 0, is deprecated. It is currently still the default
parser, but that will be changing. NOTE that switching which parser you use
could require changes to your snippets--see the previous section.

To continue using the old parser, set g:snipMate.snippet_version (see
SnipMate-options) to 0 in your vimrc.

Setting g:snipMate.snippet_version to either 0 or 1 will remove the start up
message. One way this can be done--to use the new parser--is as follows:

let g:snipMate = { 'snippet_version' : 1 }

This PR proposes a SnipMate settings file, in which the snippet version is set explicitly in order to remove the startup message. It is set to 0 as it's still the default version.
