[OE-core] Save the day OEDAM April 7 (after ELC and YP devday)

[Philip Balister]

We are arranging an OpenEmbedded developer meeting on April 7, 2016 in
San Diego. This is after ELC and the Yocto Project developer day on
Thursday. (This is more a training day)

We will publish more information as we work it out, but we did want
people to know so they can schedule travel.

If you have suggestions for this you would like to cover at the
developer meeting, let us know.

Thanks,

Philip
