Jon Siwek 47500ceef4 Add a test that checks each individual script can be loaded in bare-mode.
Fixed most @load dependency issues in the process.  The test is still
failing in a "known" way due to hot.conn.bro and scan.bro.

##! This script can be used to extract either the originator's data or the
##! responders data or both. By default nothing is extracted, and in order
##! to actually extract data the ``c$extract_orig`` and/or the
##! ``c$extract_resp`` variable must be set to T. One way to achieve this
##! would be to handle the connection_established event elsewhere and set the
##! extract_orig and extract_resp options there. However, there may be trouble
##! with the timing due the event queue delay.
##! This script does not work well in a cluster context unless it has a
##! remotely mounted disk to write the content files to.
