Generation fails on dbus arg names with dashes about haskell-dbus

[LeifW]

There's also a

    <method name='GetSnapshot'>
      <arg name='config-name' type='s' direction='in'/>
      <arg name='number' type='u' direction='in'/>
      <arg name='type' type='(uquxussa{ss})' direction='out'/>
    </method>

in that file, which causes the generation to fail with:
Illegal variable name: ‘type’
since type is a Haskell keyword.

@LeifW Yeah, I am actually aware of this.The actualy argument name doesn't really do much , so it is generally safe to just remove the dashes.
