Refinement of LiteMarket (#479)

* split into two function to access the pool value as number

* rename function

* changes to the exported object

* removal of totalLiquidity: this value was only set for binary markets and it's value is identical to getPoolvalue(contract)
* pool: set in the same way as in the "Market Overview" from contract-info-dialog.tsx now
* totalShares: total shares of the contract. It's value is equal to the old "pool" value in case of binary markets

* update docs

* removal of totalShares
