MISP XML format fixed - REST API access

The XML format parsing has been fixed. (from old "value1" tag to "value" tag)

You can now fetch directly the XML file via the MISP REST API:

python misp-bloomfilter.py -u https://misp.server/ -a <your auth key> -d ../db/ -t ip-dst

Options -u and -a added.
