Now that we're highlighting the currently selected preset in the

Type menu, it looks faintly silly that Fifteen doesn't have any
presets other than Custom: you open a Fifteen window in its default
state, and the Type menu appears to be telling you it has a custom
size! Fixed by adding a preset for the default parameters.

I'd quite like to fix this properly by revamping the presets
mechanism in a way that _enforces_ that there must always be a
preset which matches the default parameters, but that's more fiddly
than it sounds. For the moment, this change fixes the only
externally visible infelicity in the current game set.
