Included jsprf for JS_vmsprintf prototype.

Fixed long delay (virtual hang) when shutting down (deleting event sbbs_t) caused by unnecessary call to hangup().
Events destructor now displays "BBS Events" rather than the last event node number (cosmetic only).
sbbs->output_thread only shows stats if bytes were sent (cosmetic only).

Changed putnode to retry writing up to 10 times before erroring out - hopefully solving EDEADLK problem with Linux/smbmount/Win2K server.

Added underscores to local 'and' and 'or' variables in guruexp() to (hopefully) solve conflict with new GNU CC.

Fixed problem over-writing registry settings when closing before startup timer fires.

Changed the way socket errors are test/displayed with WinSock (values more inline with Unix sockets).

Incremented version to 1.31.
