Accessibility fix for JAWS screen readers

Browse source 
ace.js: removed the role 'application' from innerDocument.body. JAWS
do not read any text from the edit lines if this role is set.

domline.createDomLine: to give JAWS the ability to read the lines
correctly, it is required to set the attribute 'aria-live' to
'assertive'.
