Handle `-e` / `-E` arguments.

[tecosaur]

By using -- in the shell alias, we can get flags to be included in ARGS

alias juliaclient='julia --startup-file=no -e "using DaemonMode; runargs()" --'

This way one could do juliaclient -e 'println("Hi")' etc.

I imagine DaemonMode's runargs() could be extended to recognise -e, -E, and --project perhaps?

This is great idea, I hope to implement in the following days, it is not a difficult one.
Thank you for the suggestion.
