Mark single overtaking events as invalid

[Natenom]

Wenn man sich nach einer Fahrt die Daten online ansieht, wäre es schön, wenn man einzelne Punkte löschen könnte, wenn man z. B. weiß, dass ein oder mehrere Messungen falsch waren, aber trotzdem bestätigt wurde.

Since we keep the original data file and don't want to edit it, but be able to reimport it, we'll have to do this a bit "more complicated". But in the end it will be simpler because it is predictable:

Editing a track, anything about it, will not alter the data. Instead, we "remember" what was edited, e.g. which events (timestamps) to ignore. Then we reimport the track, but the importer will read this information and modify the contents accordingly.

• Extend database schema to include modifications to apply on the track during import
• Extend track processing to apply those modifications
• Build UI to configure modificatoins

These modifications should include:

• ignoring a single event
• ignoring away a range of the track (based on timestamps, perhaps), basically manual privatization
