It needed inventing "injectable" placeholder the values of
which would be injected into the placeholder replacement
data source at appropriate times (and removed again later).

The list of valid injectables is in gmMacro.py, as with
other types of placeholders. The syntax is "name::::max length".

Instances of the cLatexForm class now inject
"form_name_long", "form_name_short", and "form_version" into
the placehoder data source just before placeholder
substitution. This also required passing the cFormTemplate
instance to the actual form instance from which it was
created such that the instance knows its template (and can
thus query it for the name/version information). Other
cFormEngines can do so as well as needed.

Done in git head.
