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.

Since the 2.13.11, we've had the ability of implementing engravers using Scheme only.  However, this currently has two limitations: such engravers may not be directly \consisted in, and no proper documentation support has been implemented.

Read for example the following discussion, where an engraver had to be rewritten in C++ just because of these limitations:
