plugins/formatter-nvim: init

[Overloader6]

Add support for formatter-nvim

TODO:

• Look for missing formatter packages (help apreciated)
• Allow user to choose custom formatter packages
• allow disabling auto install of formatters

[Overloader6]

The only thing still missing are some packages. I couldn't find packages for all supported formatters, in part because some seem to be old and unmaintained

I forgot to run tests etc
