Fix importing a corrupt .hs file overwriting the existing scripts even if the corruption is detected.

Also, fix script import possibly going haywire if you run two copies of Custom
and import scripts in both at the same time! This is because all instances of
Custom share tmpdir, which we really must fix!!
