It makes much more sense to consider only the mining fee, for the absolute fee check, as it is volatile and amount-independent. The service fee is in % and predictable.
The default value is equivalent as before (1% of the default `auto-liquidity`, given that the previous value of 2% included the 1% liquidity service fee). Previous option is deprecated and explicitly rejected.
A task has been added to generate a BuildVersions file
when building the project. Project's version can be
found in that file at runtime.
Also centralized declaration of the dependencies
versions to buildSrc.
