Add more file-types to the file table.

[kyle-wannacott]

This is a good beginner issue.
I have a few file-types for single line comments. But there is a large amount of programming languages to support.

Select a language not already on the list and add the single line comment for the language.
For example: file['haskell'] = '--'
You can get the file-type for a corresponding file by using filetype = vim.bo.filetype and print(filetype)
