[Bug #6979] All changeTheme events are bound to meta manager now
[Bug #8173] #setAutoScrollIntoView and #getAutoScrollIntoView made public API
[Bug #8173] open and close node function without auto scrolling capability made public and set more explicit name
[Bug #8173] since #setAutoScrollIntoView is public now and the user could changed the default value, we have to re set to the original value.
