Preserving new lines at the end of the template file (fixes #37)

[liarco]

This PR fixes #37.

Implementation details:

• the comment parser now returns a third array value with the number of new lines at the end of the given comment
• the initialization function runs the parser before setting the new lines count and EOL format in order to base its decisions on the template file content (if available)
• tests have been updated to support the new parser feature and check that both UNIX and Windows EOLs work properly

I hope that this can be useful, please feel free to ask for changes or any further information.

Thank you for your time.

Hi @Stuk, I'm sorry to bother you, but do you have any news about this?

@Stuk This is really useful feature

[liarco]

Thank you @MaxGsomGsom, unfortunately I'm not receiving any feedback from @Stuk. Maybe he's busy or doesn't have the notifications enabled.

I don't think @Stuk is active with this project in the last few years.

@liarco I am willing to pull this change in [my fork] but since this is a breaking change for existing repos, I'd plan it for v4. Would you file a corresponding issue there so that we can discuss the design to align with other things I want to add?

In addition to the above, the new version I'm working on - 3.2.x is introducing a single-object based config for the rule and it would allow to specify the comment in a header while you define the minimum required empty lines behind it in the config itself - thus no need to keep empty lines in the file.
