don't export the mbox
this wasn't a good idea as the mbox contains sensitive data (IP addresses, hostnames and whatnot). Not good to publish on the web. Reminded by Stefan
simplify the makefile
move the logic of the export to gotmarc, where it's easier to set up the correct env. While here improve the makefile to generate the images and the copy the style only if needed.
parallelize exporting
mexp is the slowest part of the pipeline. Try to speed it up by paralellizing it. this adds a `pe' scripts that sits in front on N mexp childs and dispatch threads to them, while still outputting the unchanged lines for mkindex. Unscientific testing has shown that this effectively reduces the time for a full export, even if not linearly. (4 jobs cut the time in half, 8 jobs was just barely faster)
add `gzip' target to recursively compress the generated pages
should save some bandwith when used with httpd(8)' gzip-static; added as a makefile target for ease of memory.
