Fix webpacktools.runtimes only catching 2 total runtimes when there are

more than two

Changes webpackTools.runtimes[chunkObjectName] to be an array of
runtimes using that name, rather than before where subsequent runtimes
would be accessed like `webpackTools.runtimes[chunkObjectName + "_" +
index]`

Spacepack __namedRequire is renamed to namedRequire
