Added the 'both' option which will replace 'chocholate'
Added the 'Map' option, which will replace the current AscensorMap option,
this option accepts an array of pairs. The option still relies on the plugin
internal representation of the AscensorMap, i.e. we're only allowing the client
code to use a more sensible notation.

__WARNING__: element order represent the order in which
the child elements are defined in the container (the ascensor), not the order
in which the child elements are declared to the plugin (i.e. ascensorFloorName).

TODO: We could pass an object defining per-workspace coordinates, e.g. {'top': [1, 2], 'left': [2, 1], ...}
