[jboss-as7-dev] cli terminal changes

["Ståle W. Pedersen"]

hi, im the one to blame for jreadline. currently you can runtime 
disable/enable history (Setting().getInstance().setHistoryDisabled(..). 
however it will only read the history file once and that is during init.

masking works as with jline afaik, but setting the mask char to "" will 
cause jreadline to insert a space instead.

these are the commits so far for replacing jline with jreadline if you 
want to test it out yourself: 
https://github.com/stalep/jboss-as/compare/cli_jreadline

- let me know if there are any issues and ill take a look.
