vis.hpp missing <vector>

[BrianS]

This header needs to have

#include <vector>

Fix issue 136. src/atomic.cpp and src/vis.cpp weren't guarding gasnet includes with #if !NOBS_DISCOVERY. Since gasnet provides no "sanctioned" way to detect if its headers are safe to include (lacks a -DGASNET) we just rely on the fact that they won't include anything nobs discovery cares about so we don't include them at all.

Fix issue 134. src/vis.hpp was using std::vector without doing #include <vector>.
