[core] huge changes to optionable API, see details

Direct access to options is no longer allowed, modules must use the
Optionable helpers instead:

* to set options, use setOptions(), or setOption()
* to get a single option value, use getOption()
* to get all current options, use getOptions()
* to query whether an option exists, use hasOption()
* to test a boolean flag, use isOptionOn(), or its alias isOn()
* to add options to modules, use addOption()
* to add platform overrides, use setOptions(v, PLATFORM)

getOptions() and friends now implicitly take into account the current
Guide.js platform overrides.
[env] git ignores transient .gz
[core] platform overrides are functional!
