Follow the .NET coding style

[mrbiggred]

Update Freshli-Lib to follow the .NET coding style. This decision was reached after some internal discussions about code styles. The only difference is we will have a line length of 140 characters. This will be a soft limit that is checked by linters but can be ignored if needed.

A high level plan of the changes is:

1. Freshli-Lib's .editorconfig should be replaced by .NET's .editorconfig.

2. Setup a an formatter to auto-format the code during builds. Thinking of using format from .NET. Run the auto-formatter for this PR.

3. Update Code Climate and ECLint configs if needed to support the new coding styles. During this step we should also check ECLint is still needed with Format being used.
