change the reference for where the interpreter is

Merge branch 'random_access' of https://github.com/ijiraq/cadcVOFS into random_access

moved here to be part of the general install, really this is part of CANFAR
switched out the hard-coding of the python binary, doesn't play well with virtualenv installs
moved to scripts directory
