sshebang ordering

[RonnyPfannschmidt]

when creating a shell script using entangled, then a shebang line comes after the location indication

# ~/~ begin <<example.md#scripts/hydrate.sh>>[init]
#!/bin/bash

in case there is a shebang it should go before the location indication

Thanks for the suggestion. This was on my todo-list.
