[TIMOB-25027] Filter emulators based off supportedWindowsPhoneSDKVersions parameter

[ewanharris]

• If the user of this library specifies the supportedWindowsPhoneSDKVersions option then we will only detect and report the emulators for that version
• Added coverage to the library. I only added coverage to the main mocha test run as adding to the others seems pointless given that they only target a single file. Current results are below, I don't believe it's enforcing any percentage right now but I need to double check (update, travis passed so yeah there is no enforcement of percentages currently)

Verification

This isn't really doesn't have proper verification steps until the titanium_mobile_windows PR is ready. So I'll update it then

[infosia]

This looks good to me. @ewanharris Do you want me to merge this? I guess the only concern is version number, I would push this as 0.5.6 as we highly likely merge #79 soon because it's critical.

[ewanharris]

@infosia Yeah I think if we merge #79 first and then this once that is merged and published. I bumped to 0.6.0 as this is technically a new feature so minor bump seemed appropriate
