Share code base

Fixes #68

The code for Firefox and Chrome was almost identical, the only differences were some fields on the manifest, and the use of the namespace browser instead of chrome

Conveniently Firefox also recognizes the namespace chrome, so the same code can be use for both.

There was one problem with the settings storage. For some reason Firefox always returns undefined when calling chrome.storage.sync.get(). This was solved by calling chrome.storage.local.get() instead. The difference between these two objects is that the data saved to sync is shared across all browsers instances where the user is logged in. I don't think this is something essential for this extension but if needed we can find a workaround for that.

thanks @juanj ! As with the other PRs I'm happy to merge it after someone gets a chance to test it

[juanj]

@cTheDragons Hey! Can you give it a try? Not much changed, so all should be working. The principal thing to test is that the user preferences are kept between sessions.

Also want to point out thet when testing the extension there is no need to make a zip file. For Chrome: https://superuser.com/a/247654 For Firefox https://extensionworkshop.com/documentation/develop/temporary-installation-in-firefox/
