Alt tabbing (sort of).

A lot of this time was spent refactoring the window system to use a windows object.

To start off, I tried adding a navigator.connection API to try and identify cellular vs wifi vs ethernet structures, however as of reading the MDN docs it turns out its not a very common API, with Firefox dropping it as of Firefox 31, and Safari never having it in the first place, I ended up switching to the onLine/offLine property, which is supported by all mainstream browsers.

Also Alt + tab is currently slightly broken, as it does not yet show a window preview, as well as not properly focusing the chosen window, however this is something I will tackle later on, as I plan on adding custom wallpaper support now.
