Update dependencies

[jamesjefferies]

Version 7 of pg wouldn't connect to latest postgres databases. Took me a long time to work out what was going wrong, before realising that the dependencies were quite out of date. These updates should all work fine.

Incidentally, I started the last week-end myself to update the old GitHub version to current Node 12 LTS and aiming to use PostgreSQL 12. The idea is to pull the versions to the state of the art versions for newcomers.
I am not finished yet to share, but I am happy to exchange some insights, yet.

Some general comments on potential improvements/fixes:
I assume that as Patrick is referring in the README.md - which is far often been seen - to MIT license, the root license file and the package.json should be:
"license": "MIT",

The blog example would be far easier for newcomers to install if we would provide something basic Linux (e.g. Ubuntu) examples:
# 0.0 POSTRESQL:
sudo apt-get install postgresql-12
sudo apt-get install postgis
# 0.1 REDIS: easier than described in the referenced install guide
sudo apt-get install redis
# 0.2 Node.js: easier than described in the referenced install guide
sudo apt-get install nodejs
# psql -U postgres - does not work, therefore the below
sudo -u postgres psql

And last but not least, we should exchange 'patrick' in the SQL dump and the examples with 'gameadmin', so no one gets confused and everyone might keep the user.

Perhaps we should generate some docu equivalent to the blog posts in the GitHub Docs dir from markdown or similar.
I do very much like the way MongoDB is providing its documentation (guess using Sphinx)
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/#install-mongodb-community-edition
They have a copy button to get the source example quickly in the clipboard and they got
"tabs" for different versions of doing the same thing (e.g. installation on Ubuntu, etc.) and so much more.
https://github.com/mongodb/docs
https://github.com/mongodb/docs-tools
Sure overkill, but hey, I might use this same tooling for the more commercial projects as well ;-)

What do you say, James? Or anyone, even Patrick, who seems to be quite busy these days ;-)

@svanteschubert I certainly think there's lots that could be updated. It's such a useful little tutorial that it would be a shame if people were put off because of things not working. Took me quite a while to get things sorted (the tileLayer url is out of date too for example) that it would be good to help others not make the same mistakes!

It all depends on whether @triestpa might have some time to review PRs etc and update the blog post

Hey folks, I'm sorry for the late reply here! This looks good to me, I'll make a not to update the tutorial with these changes soon too

If you have any other fixes locally (such as tileLayer url update) I'd be happy to merge them in and to update the tutorial text for it as well.

Ive been going through this project. Its quite impressive! Im coming across out of date packages also. Will this pull request be merged?

[svanteschubert]

@triestpa Patrick, it seems you have forgotten to merge this one. :-)
I have not forgotten, but work projects steal my time, really love to start again on your project and certainly will come back, when I have something more to merge - x-mas time is always relaxed time to play around on projects like this. Thank you, Patrick!
