New feature: Add option to choose icon location on screen

[srcshelton]

... it'd be awesome if a Preferences option was added to allow selection of icon location, such as Top Left, Top, Top Right, Left, Centre (Default), Right, Bottom Left, Bottom, Bottom Right.

There might even be a benefit in an option to allow the icon to be dragged around and placed manually (either from preferences only, or if requiring a click of the icon to cancel the active jiggle).
