2118 – Inconsistent use of string vs invariant(char[]) in doc

The docs for the full constructor use "string" in the prototype, but invariant(char[]) in the parameter description. I think it should use the same thing in both cases to be cleaner and easier to use even though they are semantically identical. My preference is "string". but the consistency is more important.
this(string filename, Mode mode, ulong size, void* address, size_t window = 0);
 Open memory mapped file filename in mode. File is closed when the object instance is deleted.
 Params:
 invariant(char)[] filename 	name of the file.

Fixed dmd 1.031 and 2.015
