* Reduced PROGMEM / DRAM usage slightly (Using defaults w/HW5: Before -> 214,668 bytes / 5,757 bytes; After -> 213,414 bytes / 5,751 bytes) * Optimized some menu options and calls * Added more string constants and implemented them where found. * Fixed some stylization * Constants should always be uppercase. * Features should use the `ENABLE_<feature name>` format. * Options for features should use the `OPTION_<feature name>_<option name>` format. * Added ENUMs for more clarity and better type checking. * Moved some defines over to `constexpr` and `const` types. These are preferred over preprocessor constants when not intended for use with `#if` and other preprocessor language.
