unify code formatting

[Blef666]

This is a proposal for a unified code formatting. The configuration is stored in .editorconfig file so anyone can change it later. If you've got any subjective, estetical remarks, be welcome to share them, I'll consider involving them.
Currently there is no possibility of creating solution consisting of both automatic code formatting in IDE and CI pipeline validation. I limited it to only IDE formatting.

No remark, any formatting is good as long as it's consistent.

Just two questions:

1. does the editorconfig file has to be so big? is it somehow automatically generated, or where does it come from?
2. does the formatting reflect the defaults in IntelliJ, or is it somehow already customized?

1. does the editorconfig file has to be so big? is it somehow automatically generated, or where does it come from?

Maybe we can leave formatting style info relevant for us (like Java & xml) ?

1. .editorconfig is that big because it's exported form Intellij. Anyone who makes code style changes in the IDE and exports them will get the same size so cutting it only to changes made wouldn't be feasible.
2. Everything is a default for Intellij except for 2 custom configs:

• alignment in multilne chain of method calls
• keeping simple blocks {} in one line
• and maybe I'll increase line length from 120 to 140

@emil-bar As I explained, cutting the .editorconfig file only to relevant file types wouldn't make any difference because it's default configuration for Intellij. However, it would introduce additional work.

Ok, well you know my opinion, I'd just keep IJ defaults ;)

Thanks @Blef666

In the end I switched back to the default Intellij configuration except for the single line simple blocks {} I think no one argues it looks better.
