Solr config

[jamesamcl]

Currently there are 2 different solr configs in the repo:

• https://github.com/EBISPOT/OLS/tree/dev/ols-solr/src/main/solr-5-config
• https://github.com/EBISPOT/OLS/tree/dev/ols-solr/src/main/solr-conf

Need to work out which one to delete, and also update in dev for multilang.

solr-5-config is what is used. The other 1 can be deleted.
