#318 Fix linebreak issues by adding Editor config file

Getting lots of linebreak expected to be lf errors on Windows

The editorconfig file supported by most editors should automatically
save files in LF file ending regardless of the OS

Recommend extensions when using VSCode editor

VSCode will recommend the user installing the Editor Config and
tslint extension when not installed.

The editor now understands the indent type and size for files
