release: 1.3.82

======

* engraver.ly: cleanups.

* etf2ly: robustness fixes, handle mac files as well.

* Smobified Translator and Translator_group, junked
Translator_group_identifier.

* \pushproperty and \popproperty withing \translator, similar to
predefining \property, ie.

	\translator { [...] \pushproperty [..] }
	\translator { [...] \popproperty [..] }

(these \pushes and \pops are delayed until instantiation, so if you do

	\score {
		\pushproperty #'basicFooProperties #'bla #VALUE1
		\context Voice { \pushproperty #'basicFooProperties #'bar #VALUE2
			[..]
		}
	}

then the setting for basicFooProperties contains both (bla . VALUE1)
and (bar . VALUE2).

* allow \pushproperty #'symbol [..] as well as \pushproperty #'(symbol1 symbol2 ... )
