Simplify DownloadURL

Browse Source 
The script was over-engineered. The new version provides the same
functionality while removing uninteresting postmortem messages.

In addition try_catch.sh has a bug that injects set +e to a sourcing
script which was propagating through DownloadURL.sh to almost all
provisioning scripts. So it is good to avoid using it.
