client: improve ability to test FW diagrams

 * Restructure code in fairwayavailability.js to seperate external data
   retrieval and adding the data into the store. Good side effects are
   that using a mutation for setting test data is easier and only
   one commit call is necessary, which means less clutter in the state history.
 * Adding an example how to use this for testing to docs/developers.md .
 * Bump copyright year for one file.

+## Hints
+
+When testing the vuex store object can be accessed from the
+webbrowsers console like
+
+```javascript
+store = document.getElementsByTagName('a')[0].__vue__.$store
+```
+
+This allows for setting test values where getting real test data
+is complicated. For example testing the diagramm for the
+fairwayavailability (tested with Chromium 73 und gemma-2019-09-04):
+
+```javascript
+data = store.state.fairwayavailability.csv
+
+data=`#time,# < LDC (164.0) [h],# >= LDC (164.0) [h],# < 230.0 [h],# >= 230.0 [h],# >= 250.0 [h]

+
+store.commit("fairwayavailability/setAvailableFairwayDepthData", data)
+```
+
+(Depends on the code structure in store/fairwayavailability.js.)
