Strings starting with number aren't parsed properly

When a string starts with a number, it results in a parse error:

1) config should parse the default config file:
     Error: Cannot parse config file: 'config/default.yaml': Error: hash not properly dedented, near "AES-128-CFB8\n  ivLength: "

To fix the problem the int regexp should be:

['int', /^(\d+)(?=\s*[,\n\s\}\]])/],
