Filter adding = before $OPTARG

[jimusik]

Found that the filter isn't working properly as stated in the API documentation. It's currently adding an = after ?Filter which is not the correct filter format.

Line 269:

query="${query:-?}${query:+&}filter=$OPTARG"

Should be:

query="${query:-?}${query:+&}filter$OPTARG"

On a secondary Note - the filter includes brackets in the API which are not allowed in the URL. Would be nice if I could just pass the brackets to BS and let it fix it when generating the URL. For now, I'll write the %5B and %5D into my own code.
