Allow the user to avoid the local plist storage for refreshToken + correct download approach

[danielgindi]

• We need to let the developer choose when to refresh and when and where to save the refreshToken - as an alternative to using the plist storage.
• Download should always be performed to disk, not to memory!

I do not know how to build this framework, there's no build script. So someone else will have to do that.

These are some important improvements... Are you planning on pulling the request?

Thanks for the pull request @danielgindi! We're in the middle of some refactoring of the LiveSDK for iOS to support cocoapods and clean up what's in the repo. I noticed you have several changes integrated into a single pull request, including: a) download to disk instead of RAM, b) enable setting/restoring sessions, c) delegate-based refresh token storage. It would be helpful for us if you can split these into individual pull requests so we can evaluate each change individually.

Well I actually have no idea how to separate pull requests on GitHub... they are already on different commits

[danielgindi]

The longer you wait before pulling the request - the more commits are added ;-) I think GitHub can't create separate pull requests

[rgregg]

You can only have one pull request per branch. You need to separate the changes into different feature branches and submit a pull request from each branch.

[danielgindi]

I've separated them - thanks!

Anyone alive here? :-)

There aren't a lot of engineers around right now due to the holidays. We'll get to your pull requests as soon as we can.
