Make tests work reliably on the Pi

Browse Source 
While the tests work well on a PC or Travis, the Pi (where I ought to be
running them!) has some issues with the timing tests. Need to relax the
tolerance of the "assert_states_and_times" method to 0.05 seconds
otherwise it periodically fails even on something reasonably quick like
a Pi 2 (less failures on a Pi 3 but still occasionally).

Also reduced default fps to 25; if the default timing occasionally fails
on a Pi 2 it's evidently too fast for a Pi 1 and shouldn't be the
default; 25 also doesn't look any different to me on a pulsing LED.

There's also a bunch of miscellaneous fixes in here; last minute typos
and chart re-gens for the 1.2 release.

Source Tools
============
.. currentmodule:: gpiozero
.. currentmodule:: gpiozero.tools
GPIO Zero includes several utility routines which are intended to be used with
the :attr:`~SourceMixin.source` and :attr:`~ValuesMixin.values` attributes
common to most devices in the library. Given that ``source`` and ``values``
deal with infinite iterators, another excellent source of utilities is the
:mod:`itertools` module in the standard library.
the :attr:`~gpiozero.SourceMixin.source` and
:attr:`~gpiozero.ValuesMixin.values` attributes common to most devices in the
library. These utility routines are in the ``tools`` module of GPIO Zero and
are typically imported as follows::
from gpiozero.tools import scaled, negated, conjunction
Given that :attr:`~gpiozero.SourceMixin.source` and
:attr:`~gpiozero.ValuesMixin.values` deal with infinite iterators, another
excellent source of utilities is the :mod:`itertools` module in the standard
