LiquidFloatingActionButton Add ability to change individual icons

I've added the ability to change icon colors so that they display smoothly, updated the podspec to completely support Cocoapods 1.0.1, and removed some build warnings that occured with XCode 7.

The only thing you'll want to check before the merge is the podspec's description and the installation instructions for the README, since it points to me rather than to you.

-Cheers!

I've also exposed LiquidtableCircle.color so that the user can set them

I also forgot to update travis to use cocoapods 1.0.1 instead, my mistake

Thank you for great contribution! It makes an error. Could you fix it?

Unfortunately I don't know how travis works (I've fixed everything up to actually running the tests themselves), but as far as I know it seems like it's failing at the testing stage.

Apparently switching from xcodebuild to xctool fixes this. More info here: https://github.com/travis-ci/travis-ci/issues/5743

I'm since fixed swift-3 support, though the build still seems to be failing
