#6 bugfixes to previous IE patch

[James Van Lommel]

Turns out I should not have tried changing

#define DEFAULT_SSPI_PACKAGE to "NEGOTIATE" (errors out on win2k3 server talking to Firefox client; works okay with IE clients though)

reverting to

+#define DEFAULT_SSPI_PACKAGE "NTLM"

per original sources.

Also added a check for NULL conentLen, just to be safe.
