Back to development: 1.3.2
Preparing release 1.3.1
Respect SOLR environment variables.
When a SOLR-env variable is set outside of the startup script, it
should be respected.
The values generated in the script are now used as default.
This makes it possible to change the configuration from outside,
for example in tests.
Run tests on jenkins.
Fix buildout so that jenkins can actually run the tests.
