calloc'ing the options object in order to not rely on uninitialized data for jumps in various places

don't copy the path if it doesn't exist

adding methods for getting the raw (pre-standardized) request path and for overriding input parameters in --before scripts

removing cruft

adding benchmarks

fixing a potential memory leak

using a separate buffer for data written by pre-request scripts, to be written before other content (and by itself if mg.interrupt was called)

adding mg.set_mimetype

Appending Lua package paths relevant to whatever script is being executed prior to execution, rather than just once when the script context is created.  This ensures that document-level scripts can find their sibling modules even if there's a pre-request script.

making status response 'meta' arguments actually optional, defaulting to generic messages

passing a copy into dirname because that method unintuitively modifies its argument

fixing build errors caused by missing headers when DISABLE_LOGGING is defined

ignoring SIGPIPE so that weird clients don't cause problems

minor cmake cleanup

adding a testing framework

adding command-line options for middleware to the README

moving URI path max definition

implementing pre-, post-, and error-script middleware functionality

removing unneeded line
