[FEATURE REQUEST]: Camouflage pin config

[tonymorony]

Option in the settings to set a "camouflage" pin. If a user logs in/unlocks with this pin a fake LOW balance will be shown (use a RNG and store this value locally...) and the config option NOT shown in the settings.

More information (ref: https://github.com/ca333/komodoDEX/issues/858):

it should work as usual just show lets say 1-5% (a little bit randomised probably) of users balances and you should be able to send actual transaction or perform an actual swap - just as max will be used this lowered value of "fake" shown balance.

So to perform actual transactions same set of coins should be activated and actually user should have some balance for it or attacker might not believe user.

Imagine the case when somebody robbing you or kidnaped and forcing to send your crypto to him.
