Bare doubledash

[mdavis199]

Add a "--" command line option so Cmder can be launched with any conemu command. The command line after the double dash is forwarded as is. Quotes and spaces are retained so that there is no need for complex escaping.

It greatly simplifies launching project-specific consoles/commands without requiring that Tasks be created for each project.

For example:
This is a batch file that I am using in a real project where I am updating a software package. This batch file launches Cmder with (1) a console running Docker with the original software, (2) a console running Docker with the new backend software, (3) a console running a development node server, (4) a console that I work from.

e:\apps\tools\cmder\cmder.exe -- -runlist ^
cmd -new_console:d:"E:\Projects\mfd\original-docker":t:"Docker Original" /k "addpath docker && docker-compose up" "|||" ^
cmd -new_console:d:"E:\Projects\mfd\newui":t:"Docker NewUI" /k "addpath docker &&  docker-compose up" "|||" ^
cmd -new_console:d:"E:\Projects\mfd\newui\frontend":t:"Yarn Start" /k "addpath node &&  yarn start" "|||" ^
cmd -new_console:d:"E:\Projects\mfd\newui\frontend":t:"newui" /k "addpath node"

It can have spaces in paths and names without escapes.

Note:
I have not updated the Readme or the popup help window. I have not removed the "/x" option, though it may not be needed now.

Thats crazy! Thanks for the PR. I will look at it later, watching football today.

@mdavis199 Thanks, I can finally ditch my intermediary batch files!
