* There are three pieces to this CL (sorry):
1) Move and/or rename some constants into emailcommon
2) Move Utility to emailcommon, moving the few UI
related utilities back into Email (FolderProperties
and UiUtilities)
3) Remove all references to resources from emailcommon
* The three pieces relate in that, between them, they allow
the emailcommon static library to compile cleanly
