Add test case for mbb severity and fix error

[thomascobb]

Also, when using alarm.MINOR_ALARM instead of "MINOR" I got:

Traceback (most recent call last):

Regarding using alarm.MINOR_ALARM, yes, I'm afraid that's how it works. I think that putting in special hacks to work around this would be a terrible idea! At least we get a pretty straightforward error message...

I was wondering if this was new behaviour, as the original docs and your updated docs both mentioned using alarm.MIINOR_ALARM when specifying mbbi/o records...

@Araneidae can I merge this one and make a 3.0 release? I think everything else is sorted now

Go ahead!
