SHL-159 - Allow usercode to access shell command line args

Also update gradle.properties to publish 1.1.1 snapshot
Looks OK. However I have this doubt:
Say a client wants to actually execute a command and then quit, something like:
xd-shell stream create --definition time|log

what the user wants is to actually create a stream, but I think the code will identify "--definition" as a parsedArg 

what do you think ?
