Trireme 0.8.7

A few critical issues which were breaking Apigee customers' apps.

Issue 124 Add the "_implicitHeader" to the HTTP adapter,
because this undocumented function is used in some very common Compress middleware.
Issue 125 Fix command-line processing, which was swallowing
arguments that start with "--" even if they appear after the name of the script. This broke NPM.
