Added output of indication that the initialisation of a service process failed on Windows debug mode.

Fixed crash in service process Windows debug mode due to write to literal string memory. Can work depending on application run protection mode. But is BAD.

Added CLI method to set a variable somewhere directly, using PVarType, rather than simply calling a notifier function. e.g. a boolean or integer are very standard in how the are handled.

Added template based "reference" PVarType, one that contains a reference to a variable somewhere else that is set whenever the PVarType is updated.

Tweaked PArgList usage so can set the usage prefex in the output string, defaults to "Usage: ".
