drop trailing space on Date header values

fix the Date header on the raw email too while here also drops a useless chomp

add a nav at the end of each mail for raw body and thread link

create temp files in /tmp and don't allow writes to "." there's little point to use pledge/unveil and then allow the program to modify itself...

refactor the "thread header" into a separate function

refactor how external file are slurped

refactor the parsing into the module change the mscan format string to siplify the parsing, and refactor the parsing code into the module for reuse. pe is an exception in that it doesn't care about the format string, it just need to decide if the current line starts a new thread or not, that's why it doesn't use the newly introduced `parse'. The new format simplifies pe too though.

mexp: defer skip test after $tid is set otherwise we run with an undef $tid when processing new replies to existing threads.

pledge and unveil the scripts

drop needless mkdirs

mexp: handle the body line by line

move the mid -> path code to a sub in the package

drop needless chomp

move some common code in a module
