Dos and Unix line endings are now both supported (previously on unix line endings were supported) and can be accessed via the `fileformat` option. The file format will be automatically detected and displayed in the statusline but can be overriden. Possible values for the `fileformat` option are `dos` and `unix`. Closes #443 Closes #755
