Enable JLine Event Expansion

This feature enables using the Event Designators inside the Asadmin Multimode.

An Event Designator is a reference to a command line entry in the history list.

This is enabled by default.

If this feature is enabled, all \ characters are treated as escape characters and they are removed before running the command. If you need to pass \ into an asadmin command, you need to escape it and turn it into \\. This needs to be done even if you enclose the string in quotes.
