Compounding staking rewards

[micahalcorn]

At least one user has requested that we add an optional feature for stakers' OGV rewards to be automatically converted into veOGV so that they are compounded. I agree that it's frustrating to have to periodically create new stakes when collecting rewards, particularly due to #265 and #266, which make it impossible to ever get to a 0 OGV balance by staking (after the firs time). I imagine that a true auto-compounding feature would be a significant change to our current veBalance calculation and I'm not sure how it would work. It does make logical sense though that a user could receive a "compounding bonus" for electing to never be able to collect rewards until the entire stake unlocks. A simpler compromise might be to make it possible to "collect and stake" accrued rewards instead of having to collect them in one transaction, then stake them in a second transaction (and deal with the inevitable collecting that occurs when staking again). #265 basically does the opposite of what the user wants in this case. There is an accrued rewards balance, and she wants to compound it rather than being forced to either collect it or leave it alone.
