[qgis-qwc2] Transitioning from QWC1 to QWC2

[Adriano Kaulich]

Thank you Sandro for your reply, it got me onto the right track. For 
anyone wondering, here is how I made the transition.

When I first executed the 'yarn run prod' command from within the the 
demo app directory, I copied the results (the 'prod'-folder) into the 
/var/www/html/ directory and got the QWC2-Demo-App running under 
'http://localhost'.

I also had a QGIS-Server running a project of mine, and get a valid 
response from it under

http://localhost:81/cgi-bin/project/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities

What I had to do is paste the first part of the project-URL, 
http://localhost:81/cgi-bin/project/qgis_mapserv.fcgi, into the first 
entry in themes.config.js of the original qwc2-demo-app folder, adapt 
the first entry's properties accordingly (title, attribution, etc.), 
delete the other, unwanted theme entries that are all part of the demo 
application, and rerun 'yarn run prod'. And then replace the files in 
'/var/ww/html/' with the newly created ones. Under the URL 
'http://localhost', there is now my QGIS Project with the shiny new QWC2 
look.

I don't know if setting this up was easier back then with QWC1, but it 
certainly looks nicer now :)

Great work, thank you very much!
