Fixed validation errors:

• 'seg' contained directly in 'entry' by enclosing them in 'etym' (39 instances);
• character data contained directly in 'entry' (28 instances);
• @osisRef value that didn't match the pattern;
• converted spurious @lemma/@strong pair into @n;
• Fixed 6 out-of-place gramGrp elements and 2 out-of-place seg elements.
