installation automation

[cjslep]

Branching from #56 by @aschrijver:

4. Install automation

(For this I need to know more about what the outcome of the install process is, in terms of folder/file structure, etc.)

There are a number of steps that can be further automated:

• Copying the /templates directory to the right location.
• Putting the certificates etc. in a /security subdir.
• Creating the static site dir, if it does not exist.
• ...

This should cover both the development and deploy (prod) cases.
