* remove non-mainnet check for PIBD requests
* add first version of get blocks function
* .\api\src\foreign.rs
* add a max value to get_blocks, documentation
* typo
* updates based on feedback
* Minor update for foreign api docs. Peers seems to be no longer needed as an arg in the grin_api::Foreign::new.
* This changes foreign_rpc and owner_rpc modules to public so the helper modules for the rpc clients can be accessible in external projects.
Tx pool takes some parameters as trait objects. It's not an idiomatic Rust code, in this particular case we should use generic types. Trait object makes sense when we accept in runtime different concrete types which implement the trait as a value of the same field. It's not the case here. Trait objects come with a price - instead of method dispatch in compile time we have to accept runtime dispatch. My guess we did it to not clutter the code with type parameters, which is understandable but still suboptimal.
* Node API v2
* Update gitignore
* Add get_pmmr_indices method
* Add Foreign and Owner API each one with specific secret
* Fix failing tests
* Revert to 'Option<u64>'
