[Feature] Localization string engine

as described in this guide : http://pgas.freeshell.org/mirror/ABSlocalization.html
localization is possible with dollar sign before double quotes
```
cd $var || error $"Can't cd to %s." "$var"
read -p $"Enter the value: " var
```
maybe amber can add this sign easily.

this may make it possible in the future to generate translation files easily directly with Amber or with integrated function
