Elm entry: Expose the internal textblock object.

This commit introduces two new API: elm_entry_textblock_get and
elm_entry_calc_force. These two APIs can be used to manipulate the
textblock object inside the entry in a safe manner. This exposes an
interface that wasn't available before letting do new and cool things
with entries.
