How window.APP_CONFIG is generated

Given a set of environment variables and a prefix (default APP_CONFIG_):

• filter the ones whose name doesn't start with the prefix
• strip the prefix from the name of the remaining variables
• define the window.APP_CONFIG object using those key-value pairs

Example. Given the environment:

APP_CONFIG_KEY_0=VALUE_0
APP_CONFIG_KEY_1=VALUE_1
NON_PREFIXED_KEY=VALUE

the following window.APP_CONFIG is generated:

window.APP_CONFIG = {
  KEY_0: "VALUE_0",
  KEY_1: "VALUE_1"
};
