Use long type for GEXF with Python2 long or Python3 int.

[hagberg]

GEXF has a "long" integer type. Use that for Python2 longs and the standard Python3 int.

Addresses #940

A few days after making the changes I have had some issues with properties showing up as lists when they were really strings or longs. I have no clue if this is related to this issue but it would be worth keeping an eye on.

EDIT: I reverted the changes and ran and am still having the issues. IT may be an issue with gephi's import script.

Could you be more specific about this issue? Maybe an example?

I don't think it was networkx. I think gephi noticed a time in the attributes and started acting weird. The .gexf it's self looks fine.
