++Vitoco's version of NSIS Service Lib

I've modified current version of servicelib.nsh (Version 1.3 - January 5th, 2006 by dselkirk) to fix some bugs and to add an option I required.

My modified script is available at http://www.vitoco.cl/nsis/servicelib.nsh. I don't want to change the wiki by myself as it seems that others have their own patched version of this script.

Notes

• Administrator rights are required to run the installer.
• It is now possible to specify an arbitrary name to be displayed in the services console other than the service name itself. This is done by using the new display parameter. [ref].
• machine parameter was renamed to depend [ref].
• To let a service run as a specific user other than "Local System", that user must be granted the right "Log on as a service" using the Local Security Policy console, before trying to start it up [ref].
• Fixes includes:
  • CreateServiceA data types when some fields are (not)null [ref].
  • a missing goto at the end of a "case".
• Tested on WinXP and Win2K3.
