Eliminated race condition at end of ctrl_thread if xfer_thread is still running caused protection faults.

Nodes are re-run automatically and configuration reloaded in sbbsctrl after wizard runs successfully.
Wizard loads at more appropriate time during "first run".

- was allowing output buffer to fill completely instead of only half-way like VXD method.
Added log output when output buffers are full (on 9x and NT based OSes).

Fixed possible memory leak if disconnected after AR search.
Sysops can now set exemptions and flags they don't have as long as their level is equal or greater than the user's.

Failed login delay now occurs BEFORE response to client (per RFC2577).

Now restricts PORT command to ports >=1024 as recommended by RFC2577 to eliminate FTP proxy bounce attack to well known ports (e.g. SMTP).

Move internal sysop page (random tones) from getkey() to inkey() and replaced the short tones in msgabort() (every 100th call).

Changed strip_ctrl() and strip_exascii() to return the modified string.

Changed strip_ctrl() to JUST strip control chars and created prep_file_desc() to do what strip_ctrl used to (much more than just strip ctrl chars).
Updated crc32() to auto-detect ASCIIZ string length if no length is specified.
Updated various string loops to check for NULL rather than using strlen().

Added 32-bit CRCs for version and copyright strings to defeat the lame-o hex0rs.
