Added well formatted content for gitignore and gitattributes

[hindermath]

I think it is good idea recommendation to insert well formatted content for the two files gitignore and gitattributes. I use tis in my projects where I use this files. The content I use is creatable from
https://gitignore.io/ and https://gitattributes.io/. I configure them with the keywords DELPHI, FreePascal, Pascal and/or Lazarus.
Here are the exact URLs for getting the correct formatted content of this two files for every project you are using this files:
https://gitattributes.io/api/delphi%2Cpascal
https://www.[toptal.com/developers/gitignore/api/delphi,freepascal,lazarus](https://www.toptal.com/developers/gitignore/api/delphi,freepascal,lazarus)
