allowing shebang #! when converting to script

[pfarndt]

My first notebook cell starts with a shebang, e.g.:

#!/usr/bin/env julia
versioninfo()

When I convert this notebook to a --to=script the output starts with a new line followed by the she bang:

#!/usr/bin/env julia
versioninfo()

However the newline prevents the shebang to be interpreted as such. The first new line (0x0a) should be omitted.

Similar too: #376

It's an issue with this template.

Gobbling some of the whitespace might work. Like:

{%- extends 'null.tpl' -%}

{%- block input -%}
{{ cell.source }}
{% endblock input %}

If this would do the trick it would be cool!
