Generate localization files for iOS and Javascript (jquery globalize).

Localize.h

#pragma once

// Use this macro to localize strings in "common" code (code that is used in iOS and Javascript)
#define AIMLocalizedString(string, description) string

localize.sh

#!/bin/bash
#
# Generate localization files for iOS and Javascript.
#
# How does it work?
# Cross platform strings and Javascript strings are temporarily converted to NSLocalizedStrings.
# Afterwards the 'genstrings' tools is used to generate iOS localization files. These files are
# converted to jQuery localization files (https://github.com/jquery/globalize) to be used in Javascript.
#
# Attention: You need to add new languages manually at the end of the file
