Add FormatDocument command for feature files (#61)

* Add basic FormatDocument command support. (Cherry picked from @Dreamescaper with commit 66403f2)

* Included missing FormatDocumentCommand.cs file in TechTalk.SpecFlow.VsIntegration project

* Added configuration settings for the FormatDocumentCommand

* Replaced '\n' with Environment.NewLine to preserve configured line-endings when formatting a feature file

* Formatted using space instead of tabs

* Move FormatDocumentCommand class to VsIntegration.Implementation project

* fix tables formatting and cursor jumping

* add options to UI + small fixes

* Change index names
