user/jszakmeister: turn on indent guides

Get rid of my custom python setup, since indent guides are in the core
now.
user/jszakmeister: drop setting up the colorscheme

It's the default now, so there's no need for it.
user/jszakmeister: drop company-related bits

I've moved them to a separate plugin at work.
user/jszakmeister: implement a better algorithm for finding sniputil

Update my snippet template to match.
user/jszakmeister: drop the unity snippets

I'm moving them to a separate plugin so others can have them too.
user/jszakmeister: no longer need autocmd for reset cursor in man pages

This was fixed a while back, but I never took out my workaround.
user/jszakmeister: remove unused function
user/jszakmeister: add some markdown snippets

One unexpected quirk here is that in order to match how reStructuredText
is done, h1-h4 don't correspond to actual h1-h4.  Instead, it's more
like h2-h5.  I may have to reconsider that later, but that's the way it
is for now.
user/jszakmeister: don't print the commands when building snippets
user/jszakmeister: add a markdown snippet for code blocks on GitHub
user/jszakmeister: update clojure snippets

These are converted from David Nolen's clojure-snippets repo for
Yasnippets:

Point to Szakmeister's implementation of rst2ctags.
Replace syntax/mkd.vim with vim-markdown.

This also includes incorporating some of vim-markdown's setting into our
SetupMarkdown(), and adding a little extra highlighting for code blocks.
Make the default filetype for Markdown files be "markdown".

It appears "markdown" is a more common filetype for markdown files, so
it seems to be a better default.  To provide some support for mkd, just
in case, mkd snippets now delegates to markdown.

This change also means that anyone with custom mkd snippets and
autocommands needs to change them to markdown instead.

Also, we now use vim-markdown's filetype detection.  Now .mkdn is
recognized as a markdown filetype and now .mdwn is not.  This seems
reasonable since .mdwn seems unlikely to be used.
user/jszakmeister: move markdown snippets to the new filetype
Implement better embedded language support for vim-markdown.
Support embeddeding sh and vim in rst and markdown documents.
