Description

Currently you can configure jspwiki's behavior with java system properties and/or environment variables.
These values take precedence over jspwiki property files.

However, in some environments this is failing because many jspwiki properties have dots in their keynames (e.g. jspwiki.baseURL), and in a *nix shell environment, envvar names are not allowed to have dots in their name and can not be exported ("jspwiki.baseURL is not an identifier").

I ran into this issue trying to deploy jspwiki with Apache brooklyn.

The proposed solution is to replace dots with underscore, so you specify the envvar jspwiki_baseURL, and thereby set property jspwiki.baseURL.

I will attach a patch.
