Major Toolkit Update: socat and TTYd

-Both SMD11 and SMD7 are now used to create 2 separate AT command flows/streams
   -SMD11 is linked to ttyOUT
   -SMD7 is linked to ttyOUT2
-ttyOUT is intended for use with automated AT commands like the modem status parse script
-ttyOUT2 is intended for user initiated AT commands like the AT Commands page in simpleadmin or the new atcmd shell command

-Entware installation has been improved for better compatibility and smoother install.

-Added the option to try out TTYd
   -This is a web based shell console you can access via http on port 443
   -More improvements to come
