Rename modules as mentioned above.
Indent nested submodules to make them stand out.
Group foreign_procs by what predicate they implement, not by
their implementation language.

% Modules compiled by rotd-2007-02-27 and before sometimes did not
|
|
% implicitly foreign_import themselves. This meant that procedures
|
|
% exported via a pragma foreign_export were not visible to foreign
|
|
% code in the same module. (This only showed up with the LLDS backend
|
|
% since the MLDS->C code generator always inserted the necessary foreign
|
|
% import regardless of whether it was present in the HLDS or not.)
