Add integration tests for many more browsers

[craigfowler]

I'd like to test a far wider range of web browsers in the build.

I need to pick a selection of versions of the big browsers and test against each in order to ensure that they still pass tests. This includes some older versions of the browsers which I currently support.

Migrated from csf-dev/CSF.Screenplay#118

This is likely to spawn further issues, as other browser versions have poor support for various features and require special treatment.

[craigfowler]

I need to decide upon the list of browsers to support here.

[craigfowler]

Minimum supported Chrome version
56.0.2924

This version is a year old now, and given that the browser auto-updates on most systems this should be sufficient.

[craigfowler]

Minimum supported Firefox version
51.0

This version is a year old now. As with Chrome, it auto updates, so all users are expected to be up to date.

[craigfowler]

Looking at Internet Explorer, I think I will initially try supporting versions 8 through 11. However, if this is a problem then I could get away with supporting just 10 and 11.

The difference in market share between 8-11 and 10-11 is minimal. It's a nice-to-have to support the older ones, but it really isn't a big enough deal to break my back over it.

Still outstanding at this point

• Edge
• Safari
• Opera

I think that these two will need a different API, in which case they'll be kicked into a totally different project. I'll mention them just in case though.

• Android Browser
• Opera mini

Microsoft Edge
I want to support these specific versions:

• 20.10240
• 25.10586
• 38.14393
• 41.16299.15

[craigfowler]

Safari
I'd like to support these specific versions for desktop Safari:

• 10.0
• 10.1
• 11.0

[craigfowler]

Opera browser
The oldest opera version I'd like to support is 43. That's a year old.

[craigfowler]

All of the possible browser configs have now been added. I haven't been able to support Opera at all (no Sauce Labs support).
