BUG #15100: Increate ColorMapEditor dialog width.

Making default width for the ColorMapEditor dock panel to be large
enough to not need horizontal scroll bars.

Also updating all dock panels that we expect to be docked vertically to
not allow docking on the horizontal dockable regions -- improving
usability.

BUG #15060. Fixed issue when using TemporalShiftScale.

The problem was that when the current timesteps changed, we didn't snap
the current time to the new timesteps. That meant that we continued to
show the same old timestep even though the pipeline timesteps changed.
We fix this behavior by ensuring that we snap to a valid timestep when
the timesteps change and the animation is in "snap to timesteps" mode.

Added placeholder text to Chart Title widget to indicate using ${TIME}
for time. Also added the same to the tooltip.

This added a new xml hint "PlaceholderText" to add placeholder text for
pqLineEdit in pqStringVectorPropertyWidget.

Python syntax highlighter ctor highlights text

This is so that the text loaded into the text area (i.e. from the
ParaView state file) will have syntax highlighting before the user edits
the text area.

find_python_module() API instead.
