Don't check for wx in the test suite.

An interaction between wx and threads was blocking certain Unix signals,
causing an unrelated test to fail for me.

We were only checking for wx to exclude the inputhookwx module from the
test run. It contains no tests anyway, so we may as well just exclude it
in all cases.
Allow docs to build without PyQt installed.

PyQt/PySide is needed to list the config options for the Qt console. But
some environments and contributors may not have it, and it's not always
easy to install. This prints a warning and skips the list of Qt console
options if the import fails.
