Events and natspec has missing information

[Alexangelj]

In some events there is a lack of emitted info which would be valuable. For example, in Create events how much liquidity is allocated with the created pool. Or in Allocate events, how much liquidity is minted from an allocation of tokens.

For natspec, it's descriptive but does not always give the context around the variable. For example, the create function natspec does not let the user know what is the valid gamma values to enter.
