Add support for /ISteamApps/GetAppList/v0002/

[josephbleau]

Hello! Thanks for the really easy to use and extend API library! :)

Change Description

This small change adds support for the GetAppList API call.

• This API is available without key, seen here: http://api.steampowered.com/ISteamApps/GetAppList/v0002/
• See also: https://partner.steamgames.com/doc/webapi/ISteamApps#GetAppList

This API is useful for applications that want to interact with other APIs such as GetAppDetails, where an AppID is expected.

Hi Joey,

thanks a lot for your contribution! I'm leaving for vacation today so unfortunately I can't review this in time anymore. Promise to look at it when I get back middle of June. Once again, thanks for your patience.

[josephbleau]

No worries, it is of extremely low importance. Enjoy your trip!

@josephbleau Overall your changes are good, thanks! However there's a few bits and pieces missing (mostly tests) before I can integrate your changes. I have prepared the additional changes in the branch of your fork. Could you grant me permission to push changes into the branch of your fork? If you are not sure how, here is the doc

Actually never mind that it seems it was enabled by default. Please review the changes I amended to your original PR:

Well at this point I'm going to go ahead and assume that @josephbleau is more or less fine with my additions 😅

I also took the liberty of adding you as contributor hope that's ok with you as well

I will release as 1.6.0 ASAP thanks for your help!
