Add bundled token icons

[hboon]

Add more bundled token icons into AlphaWalletAddress+UI.swift, in tokenImage. Watch out that the hardcoded addresses in the switch-case has to be in eip55String (i.e. the correct combination of upper/lowercase) to work correctly.

@hboon how could i determine which eip55String related to its icon?

[hboon]

Google + Etherscan :)

Note that some of them would have migrated (maybe more than once). Use the lastest address.

eg. one of the old sAUD https://etherscan.io/address/0xACa2179a884bAC7C3D0bc4131585E1B7DbDD048e

But Etherscan points to the latest near the top of that page to: https://etherscan.io/address/0xe04d8770Dc06135Dd97214ea8bcbf7B1CC057AA3

To get the eip55String, create AlphaWallet.Address(string:) on each one and print out the the result of eip55String.

@hboon i can't find any information related to psai token. also in Zeplin it route to pdai icon. also can't find peos token.

[hboon]

@vladyslav-iosdev ok. Do what you can, and can you make a list of those you can’t identify?

[vladyslav-iosdev]

didn't find any information related:

• psai token
• peos token

the rest of tokens i find.

Seems to be testnet or not released at the moment according to https://ptokens.io, so let's ignore those.

In this case you can review this task. Other tokens added.
