check_isa_ingres_vectorwise

This plugin - like many others - is a gigantic shell script. Thats not so much of a problem. The problem is that it appears to have been written for a VERY old version of vectorwise, and never updated. Right "out of the box" one of the core variable assignments didnt work. Upon contacting the vendor we got a vague answer about where that variable went. If I can get it working in my lab I will post what needs to be modified.
