Version bump to 1.6.2-alpha.
Add `rel="home"` to the home page link.  This got removed at some point.
Do network and site home links in bbPress.
Slight fix to stop bbPress from putting double "Forums" in the breadcrumb trail.
The 'show_on_front' argument should only work if the front page is not paginated.
Make sure to return the default theme layout with our default filter on 'theme_mod_theme_layout' in case the user hasn't saved a layout in the DB yet.
Add the 'custom-header' class if header text is supposed to show too.
The hybrid_*_attributes functions should allow for attributes without values and output them properly.
Adds a `hybrid_comment_template_hierarchy` filter hook.  Kind of breaking my own rule of not adding enhancements between major version releases, but I need this filter.
Bump Color Palette up to 0.2.0-alpha.
Add new $supports property to keep track of theme-supported features.
Add support for a 'wp-head-callback' argument.
Port over CSS changes from Widgets Reloaded 0.5.1.
Version bump to 1.6.2.
Merge branch '1.6'
