add search.html template msearchd will also make use of it.

move thrslice to GotMARC.pm and add it hidden in thread_header

link /search and add a form in the index pages

drop unnecessary unveil(".", "r") These programs don't need to read files in the current directory: GotMArc loads in memory some files at load time, at that point no other accesses to "." are needed.

dedup thread entry generation code

change GotMArc::parse to take the line instead of $_

make GotMArc::parse return an hash reference instead of a list of strings

set binmode utf8 for the page file handler avoids the "Wide character in print at ./mkindex line 152, <> line 2751" warnings.

fix last sender name/date in the index pick up the *latest* From/Date for the indexes, not what happened to be the last mail rendered in that thread. spotted by stsp@

mkindex: show the latest date/sender per thread

urlencode the mail/thread id reminded by semarie@, thanks!

style

use File::Temp for the index pages; specify why it's not using tmppath we can't use the tmppath pledge promise as File::Temp checks whether /tmp exists. We could unveil("/tmp", "r") and use `tmppath', but it seem misleading. (noticed after semarie@ reminded me of `tmppath')
