FIX Make shell scripts executable

[dbroeglin]

Purpose

Deployment shell scripts are not executable. For start.sh you realize pretty early and it's just a chmod +x. However, then the script runs other scripts after deployment (like prepdocs.sh) and they fail to. This commit adds an executable flag to the scripts.
