Build failed on windows with lots of EOL violations

[YamStranger]

@dmarkov Looks like we need to add .gitattributes to force EOL of the repo.

@yegor256 please dispatch this issue

@yegor256. It is known problem, qulice fail if default system EOF not like in linux. So we need add .attributes to repository for force setting Unix-like end of line to git repository.
AppVeyor use linux like EOF.
This repository will not build successfully if you install git, install maven, clone repo and just build.
Here is some examples of same problem at different repositories:
This is issue same as here jcabi/jcabi-maven-skin#24 (build failed on Windows)
same is here yegor256/takes#148
fix mast be like here https://github.com/jcabi/jcabi-aether/pull/59/files#diff-fc723d30b02a4cca7a534518111c1a66 or like here jcabi/jcabi-dynamo#43

@YamStranger build is passing in appveyor

[YamStranger]

@yegor256 AppVeyor use linux like EOF for repositories by default for all git repo - it is system configuration.

[yegor256]

@YamStranger why can't you use the same?

[YamStranger]

@yegor256. Because it out of scope this repo. So you need add this in instructions - and this is issue too (it can be fix).
Some repos already have such fixes -https://github.com/yegor256/thindeck/blob/master/.gitattributes, and some not - and it is a problem. It must be general rule, or fix for every repo or general instructions like SET JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF-8.

Developers create issues like below not for fun, but because of problem:
yegor256/takes#148
jcabi/jcabi-maven-skin#24
jcabi/jcabi-dynamo#43 (it is fix with reference to my issue)
and here jcabi/jcabi-aether#57

@yegor256 If such issues exist at other repos - this means that this issue is valid too. Please reopen issue

[yegor256]

@YamStranger hm... so you're suggesting to add this .gitattributes file to all repos?

[YamStranger]

@yegor256 Yes.
Because I remember near 5 issues with same idea (I cant find first, but I will if you ask):
"mvn clean install -DskipTests -Dinvoker.skip=true -Pqulice " fails, and reason - default EOF for windows systems.

[YamStranger]

@yegor256 Please reopen this issue and let's fix it. Build of repository should be successful when user follows all the instructions in description. Now it is impossible, and user must guess what he needs to fix (it is not obviously) and spend a lot of time just for "clone and build".

[yegor256]

@YamStranger should be fixed now, see 646c8cb

[YamStranger]

@yegor256 Now issue is fixed, so I can close it.

[yegor256]

@YamStranger it's closed already, thanks
