Show the Amount of SNX being staked before confirming the transaction

[hav-noms]

Currently users are minting then canceling their transactions just to see the amount of SNX being staked.

We need to show the amount of SNX to be staked dynamically when the change the amount of sUSD to mint

Perhaps we allow multiple inputs to staking

1. How much sUSD to mint or
2. How much SNX to Stake or
3. How much c-ratio? e.g. 780%

We need to show all of these things as well when staking

1. How much sUSD is being minted
2. How much SNX is being staked
3. How much will the new c-ratio be

I'd love to have the option of setting a custom c-ratio.

Hell yea. Would love to have this and nothing to add--it covers all 3 items on my wishlist. Currently I input my desired sUSD to mint, click Mint Now, and check the screen to see how much SNX will be staked so I can maintain a buffer of SNX unstaked to uphold my c-ratio.

@hav-noms what other info should we add? C-ratio?

[hav-noms]

Yes please. Add c-ratio label with what the users new "estimated" c-ratio will be. Of course with price movements none of these preview values are guaranteed. Probably a *note we want to display on the UI also.
