Merge pull request #3839 from juliantaylor/rnotes-update

update for 1.8 release notes
MAINT: Use a.sum(...) rather than np.add.reduce(a,...)  in nansum.

Pandas has a work around for the first case, but not the second.

Closes #3849.
MAINT: Revert "BUG: do a boolean check on casting bool to other types"

This reverts commit cf13331897acb84d0a6a118c6ba4d700905d3e3e for the
1.8.0 release. The scikit-image package makes unwarrented use of the
numpy boolean type that results in some bugs when boolean values of 0, 1
are enforced. This reversion avoids exposing those bugs and provide the
skimage developers some time to set things right.
