unneeded todo
move growler destroy handler into HordeCore
small optimization
UPGRADING isn't being updated, so reason to maintain it
[mms] Added standardized/normalized mousewheelY javascript event handling to HordeCore.

Naturally, can't use it in the one place I was thinking - viewport.js -
since that library doesn't require HordeCore.  But will probably be
useful in the future.
[mms] Add 'all' parameter to Horde_Stream#getToChar().
[mms] Horde_Crypt_Pgp#parsePGPData() now accepts a Horde_Stream object as an argument.
