BUG: Index shift drops index name

[miketkelly]

>>> idx = pd.Index([pd.to_datetime('2013-06-21')], name='idx')
>>> idx.name
'idx'
>>> idx.shift(1, freq='B').name == None
True

looks good....

can you add a release notes mention (they are now in doc/source/release.rst) FYI
(since it doesn't have an issue, just put in the note, in the bug fix section)

from pandas import Series, Index
s = Series(range(3), name='name')
Index(s).name

Returns None

@joeb1415

you have to pass it in the constructor, e.g.

Index(s,name=s.name)

it could be automatic, but not sure of a use case for this

Release notes added.
