Flow status+fixes

I've tried dividing up the changes into smaller chunks to make it easier to review the changes.

Summary:
1. Edited the regex to get the column in the format 00,00 instead of only the first part 00.
2. Added two new directives 'lint-view' and 'use-server'. I also saw that 'use-server' also was requested in another pull request, so wrote this code in the same way.
4. Added more advanced linter run rules to allow grabbing the code directly out of the view buffer.
5. Changed the view formatting and added more detailed selection through the near variable.

Feedback would be appreciated.

Note: This is the first time i come in contact with python code, so please correct me if i've written it in a way which doesn't follow the best practices for the language.
