We were saving all the actions in the config file, including those with
no accelerators set. When loading these, the empty string was being
translated to `['']` and the empty string failed to parse as an
accelerator, resulting in an annoying warning.

Enabling -ffast-math enables it for the entire process and this is a
problem for numpy which prints a warning:

```
/app/lib/python3.10/site-packages/numpy/core/getlimits.py:500: UserWarning: The value of the smallest subnormal for <class 'numpy.float64'> type is zero.

Even though SAMPLE_DURATION was set to 1/100th of a second, we were
only collecting peak level data every 1/10th second and then average
the rest of the unknown values.

The SAMPLE_DURATION is now passed to the `level` element of the
pipeline through the `interval` parameter.

We were not considering rate of clip while calculating width of
the surface in which waveforms are drawn.

Fixes #2500

This will allow the observers to be aware of undoable action types.

When specifying two clips backed by the same asset, the asset should be
added to the project only once.

When using get_toplevel_parent it's possible to get a GES.Group instead
of a GES.TransitionClip which we need.

Fixes #2580

set_selection() was called after we created a temporary GES.Group
which is used to hold selection elements. This temporary group was
interfering with our selection logic and caused this bug. Now the
group is created only when the mouse starts moving.

Fixes #2433

We used to break the drawing of ticks when we encounter ticks which have
space between them less than MIN_TICK_SPACING_PIXELS. But now we are
iterating from most frequent to rare ticks. So the 'break' is now changed
to 'continue' so that it won't completely break the drawing loop.

The dot caused by the selection Marquee still appears,
but now it's under the mouse cursor. If the user releases the mouse button it is hidden, otherwise
if the user moves the cursor to drag&drop then the
Marquee starts to be visible.

Fixes #2432

There is no guarantee that the clip's children have a track when the `clip-added`
signal is emitted.
