Onchain margin position management

[froooze]

Problem

1. Settlement is now only available from bitAsset -> BTS, but not from BTS -> bitAsset
2. Target collateral ratio only works, when a margin call happens, but not before
3. Increasing CR, needs a collateral removal first (decreasing CR)

Onchain margin tools

To cover the other side of margin trading and offer a BTS call outside of a margin call:

• Increase CR (=target collateral ratio)
• Close the margin position by selling as much BTS to cover the difference of BALANCE and DEBT
• Close margin and sell afterwards X% of the BTS from the margin position to the borrowed bitAsset

Additional parameters:

• Start date
• MSSR

Can you please elaborate a bit more on 1.-3. and what your desired functionality is?

As mentioned it's related to #156. Likely also related to #161. I'd like to have a big BSIP adding all the new parameters for bitAssets so asset creator can decide to apply what rule set.

why we need BTS -> bitAsset settlement? and how is it possible?
