* Full inline documentation.
* Enqueue scripts/styles on admin_enqueue_scripts and use hook_suffix rather than GET[page]
* Add filters to twentyeleven_color_schemes(), twentyeleven_layouts(), which necessitates adding a thumbnail URL value here, rather than generating them in the form.
* Add a twentyeleven_default_theme_options filter.
* Remove manual check for REQUEST[settings-updated], instead using settings_errors(), since we're using options.php.
* Abstract out the default link color, rather than hardcoding it in certain places.
* Use checked().
* Rename some variables and functions for clarity.
* Remove unnecessary functions twentyeleven_current_layout() and twentyeleven_current_color_scheme(), as we already have twentyeleven_get_theme_options().
* Add a twentyeleven_color_schemes action to allow for enqueueing custom color schemes.
* Add a twentyeleven_layout_classes filter, to allow filtering what gets sent back to body_class().
* Hook into wp_enqueue_scripts rather than wp_print_styles for enqueueing the color stylesheet.
* Rewrite the register_setting() callback to start from scratch with an empty array. Improve the link_color logic.
* Use submit_button().
* Use esc_attr() rather than esc_attr_e() for non-translations.
TODO:
* Implement settings sections/fields logic to allow extension of the options page.
* Consider re-doing this in a class. It'll be cleaner.
* Store a DB version so we can do an add_option(), rather than calling get_option() with defaults.
