Added get_streams function so that you can do a GET request to search with several streams
Added so that you can get several streams at once by separating the stream_id with a comma, for example GET url:port/streams/id,id2,id3
For some reason search.erl was changed, it should not be.
Took search.erl from develop, should not be changed now

'
The output of GETting several streams by id have been changed so that is conforms to the look of GET /streams
Removed a print from streams.erl and added a test to streams_tests.erl
Merged with latest develop
A missing end caused crash. Now fixed.
