Remove SDL_Pango case.
Start defining styles in a single location.

Later, attributes like sizes will be adjusted based on target screen
size.
Use display styles.
Scale the symbol icon to fit bounds better.

SDL_ttf scales the symbol font differently than the native Win32
renderer.  We need to adjust the font size of the symbol font so that
the icon fits the desired size.
Add button styles.

This is to be more consistent now that we're tracking background colors
as well.

This fixes compilation with GCC (VS2010 accepted it without the
class keyword).

Define console styles.
Add ARGB assignment operator.
Use color ARGB assignment operator.
Upgrade to LibYAML 0.1.6.

This convention is easier to remember than (whatever)_t.
