chore: disable `-extoff` flag to be set by default

[v12]

Resolves #27

In many cases IE add-ons are essential for proper application functioning (i.e., parsing XML via MSXML), so explicitly setting -extoff flag makes impossible to run test suites for such apps.

If someone requires all add-ons to be switched off by the nature of the case (which is less likely but possible), it can be easily achieved by specifying that flag in customLaunchers section of Karma config though:

config.set({
  browsers: ['IE_no_addons'],
  // ...
  customLaunchers: {
    IE_no_addons: {
      base:  'IE',
      flags: ['-extoff']
    }
  }
});

Feel free to comment :wink:

Thanks, I agree that there should be a way to change this. Could you please add some documentation, so people know that this behaviour has changed and how to get it back please?

[v12]

I've just added a section to the README that explains what was changed and how to deal with it.

Not sure about version number though. On the one hand, it is backward compatible change to the API because it won't break anything by running IE with add-ons enabled (they shouldn't have been used if everything worked), but, on the other hand, it can be considered as a bug fix. According to semver these changes require different version increment - minor for the first case and patch for the second. I made an assumption that it requires minor to be bumped. Correct me if I'm wrong :innocent:

It will be 0.2.0 as we haven't released a 1.0.0 yet, so we can make breaking changes in minor versions :)

CLAs look good, thanks!

Any updates on that? :)

+1 Please merge this!

This totally prevents running tests that depend on ActiveX controls.
