Temporarily require Symfony 2.3.7, until we can figure out why the toolbar breaks on 2.4.0.

Better handling of parsing snippets. Fixes #739.
OK, this was _not_ a good fix. It breaks travis. (see below). Removing it, think of something better.

Refactored all calls to twig's render() through our own object. Also added 'stopwatch' calls to profile them.
Remove dbcheck_ts in a different way. Hopefully fixing #732 once and for all.
Added a section 'caching' to the config. Made caching of the config itself configurable.
Using dots instead of slashes in the stopwatch. More consistent with Silex itself.
