Default to using the subtle search highlighting in my theme.

For those inheriting my vimfiles, you can use:

    let g:szakdark_subtle_search = 0

In your `vimrc-before.vim` before sourcing my -before script to override
it.
UltiSnips: add a shortcut for title references in reStructuredText
UltiSnips: add a compiler barrier snippet

Force syntax sync from the beginning of the file for Python and shell.

Some additions to the C and CMake snippets.
Add a CMake snippet to dump variables.
wip: try out vim-sexp
wip: add the makegreen plugin
wip: check the error code too, and fix the length of the bar

Note: this requires you have shellpipe setup in such a way that the
error code can get through.
wip: use nosetests for test_*.py files

Requires the machineout plugin.
