Detailed routeId instructions

[radokristof]

I have made little improvements to the README. Now it might be easier for people to find the routeId for their favorite route.

I think there is an easier way. Just hover over the selected stop on the selected route on the left, and the link will have the route ID and stopID as well. Printscreen here:

Please see last line at the bottom, where Chrome displays the link when you hover the mouse over a stop.

Thanks @zttk that works!

I will change to this method, this is really easier...

@radokristof Are you planning to update this PR?

[radokristof]

Yes, give me 5 minutes and I'll update it with @zttk instructions. Much easier method...

[balassy]

No need to hurry :)
Thank you very much!

[radokristof]

I have added a new commit, simplified the instructions a little bit.
If you find everything correct, now it is ready for merging :)

[balassy]

Excellent! Thank you very much for the contribution, I'm happy to merge it.
