Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

WindowServer: Add a WSCursor class (a bitmap and a hotspot.) Also import a bunch of cursors I drew. Only the default ("arrow") cursor is ever used so far.

LibGfx: Move StandardCursor enum to LibGfx This enum existed both in LibGUI and WindowServer which was silly and error-prone.

WindowServer: Add the ability to animate cursors This adds the ability to specify cursor attributes as part of their file names, which allows us to remove hard coded values like the hot spot from the code. The attributes can be specified between the last two dots of the file name. Each attribute begins with a character, followed by one or more digits that specify a uint value. Supported attributes: x: The x-coordinate of the cursor hotspot y: The y-coordinate of the cursor hotspot f: The number of animated frames horizontally in the image t: The number of milliseconds per frame For example, the filename wait.f14t100.png specifies that the image contains 14 frames that should be cycled through at a rate of 100ms. The hotspot is not specified, so it defaults to the center.
