templates: allow inline user styles

Allow custom user-defined styles in a styleset. The styles can take any
name, and must be under the [user] ini section. All attributes apply to
user defined styles.

Example:

	[user]
	red.fg=red
	red.bold=true

Add a .Style function which accepts the name of a user-defined style and
applies it to the string.

	{{.Style "red" "foo"}}
