This module is responsible for dispatching events.
To add a new action an entry must be added to `settingsList` & `dispatcher_menu_order`
This can also be done at runtime via @{registerAction}().
`settingsList` contains the list of dispatchable settings.
Each setting contains:
* category: one of:
* none: a direct event call
* arg: a event that expects a gesture object or an argument
* absolutenumber: event that sets a number
* incrementalnumber: event that increments a number & accepts a gesture object
* string: event with a list of arguments to chose from
* configurable: like string but instead of an event it updates the configurable (used by kopt)
* event: what to call.
* title: for use in ui.
* section: under which menu to display (currently: general, device, screen, filemanager, reader, rolling, paging)
and optionally
* min/max: for number
* step: for number
* default
* args: allowed values for string.
* toggle: display name for args
* separator: put a separator after in the menu list
* configurable: can be parsed from cre/kopt and used to set `document.configurable`. Should not be set manually

Add a submenu to edit which items are dispatched
arguments are:
1) the caller so dispatcher can set the updated flag
2) the table representing the submenu (can be empty)
3) the object (table) in which the settings table is found
4) the name of the settings table
example usage:
Dispatcher:addSubMenu(self, sub_items, self.data, "profile1")
