Michael Johnson 36353c589f - Update firefox to 1.5 
- Add Makefile.common
  o A new build/install system for gecko ports, Makefile.common
    includes many generic routines and common tasks.
  o Fix ld-run-path in all gecko's by using -Wl,-rpath,${moz_libdir}
    thus removing the need to have a startup script for ports that
    depend on gecko. [2]
  o Use system libm, nss, nspr in all gecko ports

- Add bsd.gecko.mk
  o This is the predecessor to WITH_MOZILLA=[mozilla|firefox|...]
    with a more robust way of detecting a gecko a end user wishs to
    use.
  o bsd.gecko.mk abstracts the selection of gecko-based backends. It
    allows users and porters to support any available gecko backend
    without needing to build many conditional tests. ${USE_GECKO} is the
    list of backends that your port can handle, and ${GECKO} is set by
    bsd.gecko.mk to be the chosen backend. Users set ${WITH_GECKO} to the
    list of gecko backends they want on their system.

  Port Makefile example:

  USE_GECKO=firefox mozilla seamonkey thunderbird
  .include <bsd.port.pre.mk>
  .include "${.CURDIR}/../../www/mozilla/bsd.gecko.mk"

  End user example:
  WITH_GECKO=seamonkey firefox

  We highly recommend moving away from using WITH_MOZILLA and switching to
  USE/WITH_GECKO.
