Registers a property so it can be used in the CSS file format,
on the CSS file the property will look like
"-${`name_space`}-${property_name}". being
${property_name} the given to pspec. name_space will usually
be the theme engine name.
For any type a parse_func may be provided, being this function
used for turning any property value (between “:” and “;”) in
CSS to the gobject.Value needed. For basic types there is already
builtin parsing support, so NULL may be provided for these
cases.
Engines must ensure property registration happens exactly once,
usually GTK+ deals with theming engines as singletons, so this
should be guaranteed to happen once, but bear this in mind
when creating GtkThemeEngines yourself.
In order to make use of the custom registered properties in
the CSS file, make sure the engine is loaded first by specifying
the engine property, either in a previous rule or within the same
one.

Params:
nameSpace = namespace for the property name
parseFunc = parsing function to use, or `NULL`
