Feature/1.1

Hello,

I forked your project (master branch - I should have forked your feature/1.1 branch instead but I didn't see it) and made a bunch of changes. Seems like some small effort was duplicated (adding vertcoin support). Here's what I did if you would like to review and merge back into your project:

1. Added Vertcoin support.
2. Added resources that caused the original project not to compile (missing resources)
3. Moved image assets over to use Xcode asset catalog.
4. Created AppIcon and LaunchIcon images for all required iPhone/iPod platforms and required resolutions.
5. Addressed all compiler warnings (including a couple in iToast).
6. Corrected some misspellings and grammar in the text and pool/summary views.
