Commits on Jan 30, 2014

  1. module: new switch; support multiple #! args 

    Interpreters invoked via #! only see one
argument on some environments (Linux, Cygwin)

This pull request enables a script to pass multiple
arguments,such as v8 options, to node using a technique
developed for other scripting languages (perl and
ruby).

Detailed justification and analysis in the attached
file doc/Minux-X-Switch-Proposal.md

This pull request *DOES NOT* make any changes to
the public API of modules, which is a locked
subsystem.

  3. module: strip leading lines when -x switch set 

    Factor the code that removes '#!' into a function,
Module._removePrologue.

Module._removePrologue removes only the first #! line unless
BOTH a) this is the main module (module.id === '.')
 AND b) the '-x' switch was passed on the command line.

In case both a) and b) are true, Module._removePrologue
removes lines until it finds a line which begins with "#!"
and contains the substring "node".
