DDE support

[Redhwan]

Hello,

I would like to add more DDE support for Firefox:

- Currently it supports WWW_GetWindowInfo only with item 0xFFFFFFFF which
returns the most recently active window, while IE 5, 6, 7 and 8 supports
other window indices, for instance WWW_GetWindowInfo with item 1 would
return the first window info, item 2 would returns the second window info,
while keeping support for most recently window info requests (0xFFFFFFFF)

- Also Firefox doesn't support WWW_ListWindows right now, WWW_ListWindows
returns an array of window indices for instance if a Firefox process has 3
windows (not tabs) WWW_ListWindows would return the array [1, 2, 3, 0],
that's the behavior of IE 5, 6, 7 and 8. I would like to add full
WWW_ListWindows support.

Would this be accepted in the upstream?

Thank you for your time.
