Define the GUI theme in XML

Now all images used by the various UI widgets are defined in a
`theme.xml`, removing hardcoded requirements on the size of images,
borders and sub-images and their locations. The `colors.xml` file was
merged into this new file as well.

The `<img>` element defines either a plain image, or a 9-scale that is
automatically rendered at the size of the widget when any of the `left`,
`right`, `top` or `bottom` attributes are given.

The `x`, `y`, `width` and `height` attributes determine the
sub-rectangle within the image referenced by `src`. `x` and `y` default
to 0 and `width` and `height` default to the imge size.

The `<state>` element defines in which state its images are used by
setting its `selected`, `disabled`, `hovered` or `focused` attributes to
either `true` or `false`. Only the first matching state is rendered.

The `Text` and `SpeechBubble` classes now use the same skin to draw the
bubble, as well as using a newly introduced `BUBBLE_TEXT` color from the
theme palette.
