[wildfly-dev] cli variables

[Alexey Loubyansky]

Instead of a specialized command for that I implemented linux 
shell-style command substitution for expressions (commands and 
operations) enclosed in back quotes `.

So

[standalone at localhost:9990 /] set 
$prod_db=`/some/path/:read-attribute(name=mydbvalue)`

works.
