alert_kvstore.py issue on newline

[SimonSmeets]

The alert action "save to kvstore" does not work when a mv field that is used contains newline characters.
This can be easily fixed by changing one line in the code:

matches = re.match(r'\$(.+)\$', val)
to:
matches = re.match(r'\$(.+)\$', val, re.S)

Might be nice to include in the next release.
