~~~~~
* New template tag: '{% ifexists foo %}{% elifexists bar %}{% else %}{% endifexists %}` to use instead of `{% if %}` to check if a variable exists in the context.
* Warn if you use `{% if %}` to check for existance of a variable (really warn if it triggers false if the lookup fails)
* New setting: `FASTDEV_STRICT_IF`. Set this to `True` to make `{% if %}` crash on non-existant variables. This setting will very likely break some of the Django admin, because it relies on this behavior!
* Check that the venv and pycache stuff is in .gitignore
