Remove Additional Field Separator(s) within Maltego Additional Field Values

[cmlh]

https://www.facebook.com/events/105804646278891/ has multiple "#" within its "event.name" i.e.

### \$maltego_additional_field_values is: 'event.name=\\#Flight1337 - The \\#HITB2013AMS Post Conference Party#event.id=105804646278891#properties.facebookobject=105804646278891'

Since these appear to be escaped with a double slash i.e. "#" they should be removed as part of sub split_maltego_additional_fields() of https://github.com/cmlh/Maltego-Facebook/blob/master/Local_Transforms/facebook_graphapi.pl
