doc: Fix version switcher JS with two-digit versions.

The version parser incorrectly splits by character, which means stuff
like v0.10 will be treated as v0.1, and thus the selector will never
have a selection (because there is no v0.1). Additionally, the regex
doesn't handle multi-digit versions, and would popup an error about the
wrong domain.
doc: Fix selection on version switcher.

The original compared the *path* to the current version.

Small doc warning cleanups
Make Pillow the only supported imaging library.

Matplotlib already optionally depends on Pillow (not PIL!), so it's nice
to keep things simple. Plus, there are a few minor differences between
them that will just make supporting both troublesome.
Fix ResourceWarning of Image data.

If a Pillow Image is opened and only the metadata is used, then the
backing file handle is not closed, and must be done explicitly.
add python 3.4 to travis
try removing version restrictions from conda install because they aren't being found for python 3
install owslib only on python 2 for now (this will intentionally leads to errors on python 3)
move pep8 from conda to pip section
move several pure-python packages to pip install
Fix Travis' after_failure script with Python3.
Re-pin matplotlib version.
Test Python 3.3 too.
Make OWSLib optional.

The ImportError is deferred until the classes are actually used.
Skip OWSLib tests on Py3.
