* Removed the attempts to recover from invalid syntax in npc_parsesrcfile since they can produce incorrect results (spaces in sscanf can match \n's and company).

* Made script_rid2sd report the script source directly and changed related return 1's to return 0's to avoid double script source reports.
* Added missing return 0's after script_rid2sd is used and an extra error message in buildin_set/buildin_setd.
