Title: Added support to set the initial state of individual rows

From an API perspective, this is achieved adding a new
'data-tt-initialState' attribute with the desired initial state
("collapsed" or "expanded"). This attribute is later removed
automatically so it doesn't interfiere anymore with the regular working
of the plugin.
