Resolve "Remove sound from MLAAlignment helper"

Closes #193

See merge request wombat!36

Resolve "Improve "signal strength" algorithm"

Closes #96

See merge request wombat!35

But still use fixed method "max pixel" because of performance.

NFAnalysis: Use signal strength from cam instead of own calculation.

Resolve "Data Logger: Logging delay while disabling channel"

Closes #186

See merge request wombat!33

Use timer (delta) values instead. This avoids a blocked logging loop
causing a hang of the app when switching logging on an off by logging
delay time.

Resolve "AnalysisActor: Wrong error display if file not found"

Closes #182

See merge request wombat!32

Resolve "Add general Plot module"

Closes #188 and #192

See merge request wombat!31

This is now handled by the general plotter module.

Closes #192.

In this case only the maximum # of points limits the buffer.
Move history length control in Plotter out of visible window.

This also fixes issues with changing the history length.
Also fix change of max # of points.

Add EventRate as plot parameter for EventMonitor

Do not send GuiEvts in DataLoop but set dat attribute which is only read
by EventMonitor. This saves the generation of GuiEvts for ALL modules.

Update EventMonitor accordingly.

Currently we can only listen to ONE data src. This needs to be extended
in another branch before extending the plotter module

Unsolved: Subscription of notfications from ALL modules....

Change PlotParameter map key to ModuleId instead of ModuleEnquer

Add RemoveTrace to GraphBuffer

This handles time-based plot traces with history
