Moved the file under the Source directory to separate it (and future files) from the text files and Git files.
Moved the Icon and Utilities classes from PartLister and made them more generic.
Merge branch 'refs/heads/FuelBalancer'
Making things more consistent. The Fuel Balancer was stuck using the old version of Window.cs.
Moved the call to IOUtils.GetFilePathFor() inside Icon's constructor.
Added the resize functionality to the base window.
Tweaks to make it work with the Part Lister.
Added license statements.
Added a GetValue method for doubles.
Added a close button.
Changed to use the Clamp methods from Mathf (Unity).
Added a Popup Window class: it shows a popup window when the user clicks on a button, and hides it again when anything is clicked within the popup. I tried to position it relative to the button but it would not work when the button was within a scroll view.
Added a method for when we want the entire window to be visible, instead of a portion of it.
Now draws relative to the mouse's position. Also allows passing in a style for the button.
