postcss-cli 5.0.0 release notes

Now allows passing a directory as the input (all files in the directory will be processed)
The CLI is now silent by default; added --verbose flag for if you want noisy logs
Doesn't exit watch mode when there's an error in the plugin chain
Removed non-obvious shorthand arguments (-x, -p, -s, -t, -e, -b, & -c). Also removed -v as an alias for --version.
Prevent stupid option combinations like --dir & -o, and --watch & --replace
Doesn't allow --watch when writing to STDOUT
