Custom object.d should be included by default

[ryuukk]

Right now, only the default object.d is automatically included for implicit code completion

But when developing custom runtimes, a custom object.d is used to overwrite the default one, the problem is DCD only expect one object module from the default runtime

I suspect the problematic code is here:

DCD/dsymbol/src/dsymbol/conversion/first.d

Lines 362 to 383 in 29dba75

	override void visit(const Module mod)
	{
	rootSymbol = allocateSemanticSymbol(null, CompletionKind.moduleName,
	symbolFile);
	currentSymbol = rootSymbol;
	moduleScope = GCAllocator.instance.make!Scope(0, uint.max);
	currentScope = moduleScope;
	auto objectLocation = cache.resolveImportLocation("object");
	if (objectLocation is null)
	warning("Could not locate object.d or object.di");
	else
	{
	auto objectImport = allocateSemanticSymbol(IMPORT_SYMBOL_NAME,
	CompletionKind.importSymbol, objectLocation);
	objectImport.acSymbol.skipOver = true;
	currentSymbol.addChild(objectImport, true);
	currentScope.addSymbol(objectImport.acSymbol, false);
	}
	foreach (s; builtinSymbols[])
	currentScope.addSymbol(s, false);
	mod.accept(this);
	}

It should be able to differentiate the object.d from the runtime from the custom one

• DCD should be able to create a list of every object modules
• if just one object module, easy use it
• if more than 1 object modules found, then ignore the one that comes from the runtime
