Load patched modules in new browsing contexts

[vweevers]

When chrome destroys/reloads a page and extension code (like a content script) is loaded again, it'll load the initial version, without the changes that have been made since. Reproduce:

• Generate extension with a content script
• Navigate to a page in chrome
• Make some changes to the content script
• Watch it hot reload in the chrome page, nice
• Open another page, you'll see the old version of the content script (until you make another change).
