Don't hide Histogram when in range mode

When plotting distribution for a date range instead of
for a specific activity we should not hide when the current
ride has no data (since we are plotting a range not the current
ride).
RideEditor: Stop hiding controls

The find dialog and anomalies list are now available
from the ride editor toolbar and not hidden in the
chart controls.

As a result the ride editor no longer has any chart
controls and so they are removed altogether.
Chart Settings menu is All Chart Settings

.. to differentiate from the reveal settings which
are just a small subset of the chart settings.
