    Issue 1375/3: Register scheme engravers
    
    This registers Measure_counter_engraver and Span_stem_engraver
    to make them documented and callable like C++ engravers.

    Issue 1375/2: Create Translator_creator class
    
    Previously, translators were created by copying from a context-less
    instantiation of the translator containing its documentation.  This had
    several unpleasant consequences, the most problematic likely being the
    inability to register Scheme engravers because their documentation would
    be identical to all other Scheme engravers.
    
    A new Translator_creator class takes over the task of creating
    Translator instances when called with a context argument.
    
    As a result of joining the mechanisms for Scheme engravers and C++
    engravers, ly:translator-name and ly:translator-description are
    reimplemented in a manner resembling object properties.

    Issue 1375/1: Let Translator constructor take a Context argument
    
    This is the first step towards constructing rather than cloning translators
    when creating contexts.  On its own, it does not make sense, but the change
    is large and mostly mechanical, so keeping it separate from the actually
    difficult parts makes sense.

This is not even yesteryear's news but yonderyesteryear's news.  Not
that 2 years are a lot of time at the current development speed.
