console logger - support disabling the console out. 

console wrapper - comment fixes.
file handle wrappers - allow for creation of layers of file interfaces to automatically convert ASCII to UCS-2.
shell - add CTRL-S support and change how searching for startup.nsh.
shellenvvar - zero the memory allocations.
shall man parser - input verification on the help text.
shellparameters protocol - input redirection verification enhanced, leave ^ behind when not used.
shell protocol - remove ASSERTs, fixed GetDeviceName, allow mapping of BlockIO devices, and enhanced key monitoring for CTRL-S (now CTRL-S and CTRL-C).
