Title: Ported PHYLIP I/O to skbio.io.phylip, and more!

# Not ready for merge
Relies on #672 being merged first.

# Changes

* Ported `Alignment` PHYLIP format writer to `skbio.io.phylip`, added format specification
* Added `SequenceCollection.update_ids` which provides a flexible way of updating sequence IDs on a ``SequenceCollection`` or ``Alignment``
* ``BiologicalSequence.__getitem__`` now supports specifying a list of indices to take from the biological sequence
* Added ``BiologicalSequence.copy`` for creating a copy of a biological sequence, optionally with one or more attributes updated
* Fixed non-serious bug in the k-words code: `constructor` parameter was being ignored
* Deprecated a bunch of stuff
* Updated many methods in sequence and alignment code to create new objects in a more consistent and safe manner (e.g., using `copy` and `__getitem__` instead of `self.__class__`)

See changelog for more details. Fixes #653.
