[Feature Request] User-Specified Registers

[fuguesoft]

Is it possible to tell iamb to use the unnamed register when yanking/deleting? It would be cool if it were possible to specify this in the config.toml

something like:

[settings.clipboard]
default_register = "unnamedplus"

If one wanted, they might specify iamb to always use the a register or the q one for whatever reason.
