Subject: [PATCH 105/398] LOK: added a general getCommandValues method

This method returns a JSON mapping of the posible values for the given
command (e.g. .uno:StyleApply, etc).

returns:
{commandName: "cmdName", commandValues: {json_of_cmd_values}}
I've fixed the unit test this time

Change-Id: I30b0fba8ba1db33dd79f4b46026d293b9ea72402
(cherry picked from commit 39975c477a38be613e9e162acb6de241999f0ae1)
