yanorax 06ca73c6f8 Add column_title_pressed signal to Tree node ...

The Tree node column/table form is missing the ability to
capture column title clicks easily.

Adding this functionality will give us the ability to
create functions such as sort by column, which is a common
table manipulation ability in games/apps.
