Minor fixes: matrix filter sliders reset when selecting a new correlogram. Added "invert selection" buttons to the time series selector. Filtered and NaN-correlogram cells are now rendered in background color, the boundaries of the correlogram are marked by a border. Adjusted maximum bin size for the cell distribution view. Visually aligned time series and correlogram view horizontally. Both views resize correctly now. Reverted menu fix with menu buttons. Cleaned up tests, found a bug in the builder code for the metadata: Significance level was never set.
