[WebIDL] enum

Hi,

To facilitate the comprehension of the interfaces specified in WebIDL, I think we need to have some way of specifying enumerated values.
At present we define constants and associate them with the attributes in the prose.
E.g. in HTML5 we have:

  const unsigned short NETWORK_EMPTY = 0;
  const unsigned short NETWORK_IDLE = 1;
  const unsigned short NETWORK_LOADING = 2;
  const unsigned short NETWORK_NO_SOURCE = 3;
  readonly attribute unsigned short networkState;

media . networkState
Returns the current state of network activity for the element, from the codes in the list below.

To ease the process of comprehension of the interfaces, we could have e.g.
  [EnumFor=networkState]
  const unsigned short NETWORK_EMPTY = 0;
  [EnumFor=networkState]
  const unsigned short NETWORK_IDLE = 1;
  [EnumFor=networkState]
  const unsigned short NETWORK_LOADING = 2;
  [EnumFor=networkState]
  const unsigned short NETWORK_NO_SOURCE = 3;

  readonly attribute unsigned short networkState;

Alternatively WebIDL could have the "enum" keyword with some specific syntax.
The realization of this functionality does not, however, matter as much as the need to have it specified.

Thanks,
Marcin
