Avoid creating unneeded hashes by using Hash#merge! instead of #merge.

The "row" hash created within each of these methods is modified and returned.
The intermediate hashes are unneeded since no one else can accidentally modify them.
Dont redraw the whole tree when checkbox was checked/unchecked

This was causing delays and was resulting in saving incorrect data when checking/unchecking lots of nodes in the tree very fast.  We dont need to redraw the whole tree to change the text color of checked/unchecked nodes and it's children in the tree to show user the changes in the tree. Fixed to only render the node that was checked/unchecked and it's children to show differences in blue color.
