-emu/ioport.cpp: Fixed some default setting handling issues.
* Issues were unlikely to actually manifest unless you use controller
configuration files to change specific system input defaults.
-src/emu/output.h: Added size accessor to multi-element output finder.
* std::size will work on the top rank of an outut finder now. Sorry for
hitting emu.h again so soon.
-lua: Exposed a couple more input related things.
* Exposed constructor and a few methods on input_seq required for
scripts to properly clear assignments or restore default settings.
* Exposed ioport_manager::set_type_seq which is required to configure
general input assignments properly.
* Removed unnecessary use of sol::overload in favour of optional
parameters.
* Updated documentation and also fixed a few errors.
-docs: Added description for axis setting assignments.
