lyx2lyx refactoring.
* use unicode.transform() instead of loop over replacements * telling variable names * remove trailing whitespace * documentation update * don't set use_ligature_dashes if both dash types are found * remove spurious warning, normalize indentation, and use Python idioms in revert_baselineskip()
