wibar: Modernize the module structure.
Move the burdensome legacy code into local function so the normal `gears.table.crush` module setup can be used. This fixes a couple monior issues where `args` would be ignored. This also makes a minor change to the logic. Changing the position always moves to wibar to the end of the stack. Previously, there was a minor case where it would not. There was also the case when setting the same position twice would move the wibar, which was a bug.
