Qtum core UI suggestions based on v0.18.3

[alanyu18]

1、The size of the token's logo needs to be the same as the default logo, there is a circle of background color around the logo. Need to be full circle 

Please refer to the logo size in the design draft below

2、The staking switch button should be automatically turned on if users unlock the wallet with "for staking only" checked, which click from setting -> unlock wallet

PS：Other processes remain unchanged (1) When encrypted, the Staking button should always stay on the off model, if I want to turn on it, needs to ask for password (2) When unlocked or unlocked only for staking, the Staking button could switch on and off freely

3、The icon in the prompt box is not high-definition, and you can still see the pixels If you need design materials pls tell me

4、The selected color of the transaction list（both in My wallet and Transaction Tab）should be the same with the selected tab color (The color of 1 and 3 marked in the screenshot should be consistent with 2)

Any questions pls contact [email protected] Thanks!
