  BUG: genfromtxt gave OverflorError for large integers

Fix StringConverter to avoid OverflowError in genfromtxt. Before, int(2**66) would work
(and return a ‘long’) but then np.array([2**66], dtype=np.integer) would not work and
return an OverflowError which would propagate to genfromtxt. This commit fixes this by
ensuring testing in advance whether an OverflowError will occur. In addition, this adds
an explicit np.int64 entry on systems where integer means int32. Values larger than
2**63-1 will be cast as float. This includes a regression test and adds an entry to the
release notes.
