Adding a (poor) implementation of dynamicness
Adding a (poor) implementation of dynamicness

When using Django-style `{% blocktrans %}` tags, I've enabled trivial
replacement of "variables" via a familiar mechanism.

   {% blocktrans with "value" as key %}Text with {{ key }} embedded.{% endblocktrans %}

It's poorly implemented, but functional.  Think of it as a down payment
on the real functionality.

Limitations:

1.  Only double-quoted values work.  Single quotes will break things.
2.  Only one key/value pair is accepted.  Multiple, and-separated
    pairs will come later, if and when I figure out how to do it
    cleanly (the current implentation is HORRIBLY UGLY, but I don't
    really want to write a parser.
