create menmonic / vanity aliases

[ralfhauser]

e.g. "trevi" goes for Q185382 or rather /Q185382 so ultimately
https://h2o.do/trevi
will redirect to
https://h2o.do/it-roma?l=de&i=Q185382

• "pulitzer" will go to https://h2o.do/us-nyc?l=de&i=Q18157051

• elefant -> https://h2o.do/fr-paris?l=de&i=Q1326237

Level 1) just a hard-coded list (in front-end or server wherever it is easier)
Level 2) a GUI where new aliases can be added to a database / or text file (provided they are not yet taken)

to avoid code duplication/high maintenance, created in route-validator.service.ts the function
lookupAlias

==> works, but only in the 2nd attempt !

If a city is once loaded, then the detail-window sought opens.
If a city is new after datablue restart, the correct city loads, but no detail window opens

@ralfhauser
I think that issue is with API call fountain details this is why seem that not load

@ralfhauser
check https://api.beta.water-fountains.org/api/v1/fountain?queryType=byId&idval=Q1326237&database=wikidata&city=fr-paris

10. also allow for vanity aliases based on OSM node ID e.g. https://beta.water-fountains.org/jetDeau
11. if no fountain in the current city is found by the search, in a pop-up offer to open vanity-alias
