ENV-variables get precedence over the ops-hash that is explicitly passed when calling OML4R::init

[vsercu]

line 288: omlCollectUri = ENV['OML_COLLECT'] || ENV['OML_SERVER'] || opts[:collect] || opts[:omlServer]

should be:
omlCollectUri = opts[:collect] || opts[:omlServer] || ENV['OML_COLLECT'] || ENV['OML_SERVER']
so that the opts get priority? else its impossible to cleanly switch to another oml-server than the one that is specified in the omf-ec config
