Allow configuration of vendor and module version in the welcome message
-----------------------------------------------------------------------
Key: COUCHDB-1285
URL: https://issues.apache.org/jira/browse/COUCHDB-1285
Project: CouchDB
Issue Type: Improvement
Reporter: Jan Lehnardt
The patch below allows to configure vendor and module version information into
the GET / welcome message.
E.g.
[vendor]
name = refuge
version = 2.0.0
[modules]
geocouch = 1.2.1
would produce:
{"couchdb":"Welcome","version":"1.2.0","refuge":"2.0.0","modules":{"geocouch":"1.2.1"}}
