update to build on Yosemite and run on iOS 8

[100apps]

Keychain-Dumper is an awesome tool for jailbreaked iOS devices. I made some changes to build on Yosemite and run on iOS 8.

1. changed Makefile to build more easily
2. fixed #7
3. add a build and run gif demo in Readme, for new users.

Thank you @ptoomey3

I'm not super familiar with find-identity, but it looks like -v will only return "valid" code signing certificates. That seems to exclude self-signed certificates (as are used in the rest of the Readme). I'm assuming that self-signed still works fine (give this is being run on a jail broken device), right? If so, can you update this to remove the-v?

I've tested on my devices, self-signed certificates do work.

Thanks so much for the build update. Once this is ready to merge, I'd like to build it locally, sign it with a self signed cert, and update the binary that is included in the repo. But, I currently have no jailbroken device to test it with. Would you be willing to test it? If not, I totally understand 😄.

Also, I can update the Readme to use the new make build targets after we merge this.

@ptoomey3, I have more than 5 jailbroken devices, ready for your tests. 😄

Works for me with iOS 8.4 built on 10.10.4.

Cool. I'm going to clean up a few things and get this merged in the next few days.
