Remove unused SwMiscConfig instance

Unused ever since it was introduced in 5d7ce6db
"INTEGRATION: CWS swmailmerge", and access to any SwMiscConfig members has
always been done indirectly via SW_MOD()->GetModuleConfig()->..., so looks like
aMiscConfig is unnecessary (and Oliver agrees with me on that).
