Codebase review

[w-i-n-s]

Review the whole codebase and fix errors

[Sjors]

When I create a wallet on master and then run this version, there seem to be two problems:

1. in the settings screen the other cosigner is forgotten
2. the addresses on the addresses screen are incorrect

Maybe something went wrong in the NSUserDefaults refactor commit 57f5af5?

@Sjors yes, wrong condition fixed in b5f119d

Thanks, can you squash b5f119d into 57f5af5?

Found another bug: the Show Mnemonic button no longer shows a popup.

The show mnemonic button still doesn't work for me.

Also don't forget to squash the fix wrong condition check part of 4b3d24e into whichever commit created the bug. Unless it already existed on master.

Found another bug: the Show Mnemonic button no longer shows a popup.

Fixed by rollback d9c481f. Details in #14. On changing architecture to MVVM (according to #11) we also collect all possible errors/alerts and will use enumeration for displaying.

Additional details about how it works: 3rd example and details
