  Fix potential 100 Trying duplicates.

Added the "auto_100trying" module parameter to allow the script writter to take control (from script level) over when the 100 Trying reply is to be sent back.
By default, the reply is automatically generated when the INVITE transaction is created (see 908ce1be3766d9c27bfb576e5e0cc3b4eecbee31)
Fixes #833
