feature: #235 Allow dynamic component parameter

[robwa]

Up to now, only quoted expressions were allowed as the first parameter of the {% unicorn %} templatetag.

We change it to dynamic parameter handling, any filter expression should be allowed.

Closes #235

This is an awesome contribution (and TIL I learned about FilterExpression)! Can you add a test for this, maybe somewhere in https://github.com/adamghill/django-unicorn/blob/master/tests/templatetags/test_unicorn_render.py?

[robwa]

I will add a test soon.

Is there anything else I can do for this to be merged?

[adamghill]

Hello! I'm planning on making a little edit to raise an explicit exception when the component name can't be resolved from the context. Will hopefully push that merge everything into master, and release a new version to PyPI within the next day. Thanks again for your update!
