[Design] Email spec for Alpha4

[Sheila Mooney]

I have started on the 0.7 email spec by adding in details for the  
Alpha4 features - Reply, Reply All and Forward. As reflected in some  
of the list discussions, we are still working out the full Beta email  
plan which will be eventually detailed in this spec. In the meantime,  
we needed something for Brian and Reid to get started on for Alpha4.
