Use FileReaderSync instead of FileReader in Firefox / when FileReader is not available

[D8207]

As suggested in http://stackoverflow.com/questions/22741478/firefox-filereader-is-not-defined-only-when-called-from-web-worker , FileReader is not available in Web Workers in Firefox, making my browserify'ed web worker script using filestream not work.

@D8207 I've made a patch in the filereadersync branch. Would you mind modifying your package.json to include this branch and see if it fixes your issue?

This should be possible by adding something like the following to your package.json:

{
 ...
  "dependencies": {
    ...
    "filestream": "DamonOehlman/filestream#filereadersync"
  }
  ...
}

I'm not sure how to do this; browserify just looks at require() calls and includes specified files into the bundled JavaScript from my node_modules...

OK, if you haven't yet included filestream into your package.json then just try something like this in the directory:

npm install DamonOehlman/filestream#filereadersync --save

[D8207]

No luck. This version dismisses the error message, but doesn't work either.

It appears FileReaderSync has a different interface than FileReader: its read* methods return values directly, and no events are triggered. Simply replacing FileReader with FileReaderSync won't work.

OK - I'll have a bit more of a look at the FileReaderSync docs when I get a chance...
