Timeline filter by viewport

[offtherailz]

Description

Add timeline sync with current map viewport.

This adds support list and snap times only in the current viewport

Other minor fixes:

• Clear Openlayers cache when some layer's parameter changes, to avoid old lower-zoom previews
• Fixed zoom to extent hook that didn't work for full world zoom to (typically when the bbox is calculated from the CRS and it is EPSG:4326)

it seems good.
I had only an issue with the tooltip on the new sync map button.
The tooltip changes only when you toggle the enable range button. [ ]
