Usage of DOLLARS

[jak-pan]

Make sure DOLLARS and HDX/UNIT s are used correctly. We use them interchangeably but in reality 1 dollar should be roughly 10HDX. We'll need to do changes to chainspec too to use HDX/UNIT instead of DOLLARS.

An idea. Since initial liquidity in the pool will be DAI=DOLLARS. And we're sure such pool will exist.
What if we could use it to update price of of "DOLLARS" dynamically (eg. after some period of time)
So that we don't need to keep this updated? I know that this won't be easy since RN it's const and would probably require larger changes, but it's well worth to start thinking about this.

For now we can just change it to roughly final LBP price which is 1 HDX ~= 0.1$ To keep the numbers nice.
