Make all addresses EIP-55 compliant

[fulldecent]

Bounty: make all instances of account addresses in MetaMask compliant with EIP-55. Many instances of account addresses already are compliant, and successful completion of this bounty will require finding and updating all non-compliant addresses throughout the extension.

---

The correct mixed-case address is shown (truncated, but shown) on the main MetaMask screen.

But the address shown on the QR screen is all lower case.

Almost all the QR address I have seen, they're checksum. I do not know the key difference between checksum and not, but from what I understand checksum is not really enforced, and can be either way. I believe it still would better to standardize the QR code for users/service that require it.

Not sure if this is relevant here or in it's own issue but the address copied to the clipboard from the extension widget is not complaint either but if you open the tab version it displays/copies the correct checksum address.

Confirmed still broken in latest version.
