sem-apply --set parameter cannot be repeated

[pelder-lumenix]

I tried multiple psql parameters in a script:

create role user_ro login password :'ro_pwd';
create role user_rw login password :'rw_pwd';

When I run sem-apply with multiple --set:

sem-apply --url xxx --set ro_pwd=abc --set rw_pwd=def

I get script errors. Running the script directly with psql does not have those errors. On investigation, only one of the variables gets passed to psql. (The last variable wins.)

@mbryzek : Tested your changes for #70. Everything works as I expect. Thank you.
