Remove local stacktrace paths (#170)

Problem: The exception stacktraces contain the paths of the one who
built the release.

Solution: use `Directory.Build.props` to sanitize them.

The solution was mentioned by @Dorus in #164:
[The StackExchange
question](https://softwareengineering.stackexchange.com/questions/402742/how-can-we-avoid-showing-the-literal-path-in-the-exceptions-stack-trace/421590#421590)
[The
article](https://www.codementor.io/@rowlandbanks/cleaner-stacktraces-13q3hbv2s7)
The theory behind `Directory.Build.props` is described
[there](https://learn.microsoft.com/en-us/visualstudio/msbuild/customize-by-directory?view=vs-2022).

The commit contains the following parts:

1. The change itself. It was done by creating `Directory.Build.props`
and adding a specific string to it. That triggered the automatic change
in `FactorioCalc.sln`.

2. An improvement to the Contributors Guide. It was too small for its
own commit.

3. An update to the changelog.

### Quality Assurance 
To check if things work, I've added a line that threw a generic
exception when one opened a milestone editor.
The stack trace was as follows:
```

```
The line that threw the exception was deleted before making the PR.
Fixes #164

 * Please prioritize maintainability. Aim for understandable code without dirty hacks.
