Notable fixes:
- Overlays may now be generated properly without -@
- /__local_fixups__ were not including unit address in their structure
- The error reporting a magic token was misleading, reporting
"Bad magic token in header. Got d00dfeed expected 0xd00dfeed"
if the token was missing. This has been split out into a separate message.
