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.

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.
Close some figures when tests complete.

Unclosed figures cause warnings on subsequent tests.

Make Pillow the only supported imaging library.
install owslib only on python 2 for now (this will intentionally leads to errors on python 3)
Make OWSLib optional.

The ImportError is deferred until the classes are actually used.
Skip OWSLib tests if unavailable.
Merge pull request #495 from QuLogic/owslib-optional

Make OWSLib optional on Python 3
Make floats in proj4 strings be a fixed precision.

Previously, the default precision was used, but Python 2 and 3 differ on
what that is. This causes small variations in the results.

This change is expected to fail since tests are not updated.
Update proj4 test strings with increased precision.
Update Robinson tests for increased precision.
