Bundling DEB with SERVICE_HINT set to true and DESCRIPTION set to something containing bash-incorrect symbols, leads to errors in /etc/init.d/<name> :

Steps to reproduce:
1) add {SERVICE_HINT: true} and {DESCRIPTION: "Caramba service!"} to the params map
2) bundle deb (LinuxDebBundler)
3)
$ sudo dpkg --install /path/to/pkg.deb

Here we see this line in the output:
[STDERR]: /etc/init.d/app1: 15: /etc/init.d/app1: service!: not found

looking at 15-th line of /etc/init.d/app1:
$ cat /etc/init.d/app1 | head -n 15 | tail -n 1
DESC=Caramba service!

The description is not escaped properly and that leads to the error messages and incorrect init script.

Possible solution:
fix "DESC=APPLICATION_DESCRIPTION" in template.deb.init.script to
"DESC='APPLICATION_DESCRIPTION'" (add single quotes)
