Fix ssl generation

The ssl certificate/key that are generated during the build process are
sufficient for initial testing, but production use requires permanent
certificates/keys.

This modification places the cert/key into /data/crits/ssl, and creates
the necessary symbolic links so the apache can find them.

In order to override the default certs, create the certs in a  directory
with names:
	- crits.crt
	- crits.plain.key
During spinup of crits_web, specify the volume to reference the volume:
```
docker run ... -v [directory where certs are stored]:/data/crits/ssl:ro ...
```
