DOC: fix doc inconsistency in GMM
DOC fix Isomap docstring formatting

Fixes #3692.
bug fix for issue #3526

Some of the pairwise distances do not support the additional `squared` parameter. I suggest using `sqeuclidian` and such whenever this is required.
bug fix for t-SNE (issue #3526) with new inputs

New fix following the discussion on the previous pull request. Thanks to @jnothman,  @mblondel and others ..
Remove trailing '\' and add test
Describe default metric
ENH: Patches Nearest Centroid for metric=manhattan for sparse and dense data
FIX: Wrap csc_row_median around the _get_median imputer function
MAINT: Move _get_median into sparsefuncs to avoid circular imports
DOC: Explain why the centroid of the manhattan metric is the median
Renamed csc_row_median to csc_median_axis_0
Warning for non-euclidean and non-manhattan metrics
Sparse matrix conversion depending on the type of metric

If metric is "manhattan", then store it as csc since calculating
the median is easier.
