Forbid constants on [noInterfaceObject] interfaces

Hi,

From
http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#using-localfilesystem

[Supplemental, NoInterfaceObject]
interface LocalFileSystem {    const unsigned short TEMPORARY
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#TEMPORARY> =
0;    const unsigned short PERSISTENT
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#PERSISTENT>
= 1;    void requestFileSystem
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#widl-LocalFileSystem-requestFileSystem-void-unsigned-short-type-unsigned-long-long-size-FileSystemCallback-successCallback-ErrorCallback-errorCallback>
(unsigned short type, unsigned long long size, FileSystemCallback
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#idl-def-FileSystemCallback>
successCallback, optional ErrorCallback
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#idl-def-ErrorCallback>
errorCallback);    void resolveLocalFileSystemURL
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#widl-LocalFileSystem-resolveLocalFileSystemURL-void-DOMString-url-EntryCallback-successCallback-ErrorCallback-errorCallback>
(DOMString url, EntryCallback
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#idl-def-EntryCallback>
successCallback, optional ErrorCallback
<http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#idl-def-ErrorCallback>
errorCallback);
};

This results in TEMPORARY and PERSISTENT global properties. Look in a
recent Chrome console.

This should be forbidden in my opinion.

I'll take the time later to send feedback to the File API people to see if
this can be changed.
