[sldev] Patch for SNOW-237 (When building snowglobe using -t Debug no debug symbols are retained so unable to debug crashes properly)

[lists.secondlife.com at trap.wereanimal.net]

I've submitted a patch to snow-237.

What this patch does it adds code to packaged the non-stripped bin to the 
finial packed build. It only currently works on Linux and un-tested on MAC. I 
look over the windows packaging and could not see where the stripping takes 
place on the binary.

Non-stripped bins are packaged for all build types except "Release" in 
CMAKE_BUILD_TYPE. Is there any use case where one does not want debug symbols 
in a debugging build?
