Use the node's start_mark to determine line and column.

* Elminates a lot of logic in the AnsibleComposer class.
* Update tests with new column offsets.  The rule should now be
  consistently: Column is the start of the entry's value (so for
  strings, the first non-space after the entry beginning, for dicts, the
  first character of the first key)
