Subject: Strip unused template tags by default

If there's a tag defined but not used on replace table processing,
this option determines whether it should be written in the generated
file or ignored completely.

Turned on by default, this will save a few bytes. Use commandline option
'--debug-dont-strip-unused-tags' to turn it off, e.g. when debugging
template files.
