this code is now part of Game of Trees too!
template: add -o to specify the output file
This way template can delete output file on parsing errors, which helps a lot with make(1).
fix parsing of {! !} block after content
the '{' and '!' characters were pushed back in the wrong order and so read as "!{" instead of "{!". add regress for this case, and for similar usage (02 change.)
template: fix possible use-after-free and drop the `render' sugar
if some of the tp_* function fails, the inner code could free the template too (that's what galileo does), so `tp->tp_ret' would access free'd memory! Instead, add a local variable `tp_ret' to keep track of the return code. While here, drop the `render' shortand that adds the argument call, the template_reset function and adapt the regress.
