Blocktype icons cannot be overridden in themes

[Richard Mansfield]

Blocktype icons in the view editor can't be overridden in child themes. Other images can, and it's easy enough to fix this by making thumb.php look in the current theme directory for the icons, instead of looking in the blocktype's base directrory.

    Allow blocktype icons to be themeable (bug #815603)

    The current theme is now searched for the blocktype thumb.png icon.
    This change also moves the existing blocktype icons from the blocktype
    base directory into theme/raw/static/images. To ensure 3rd party
    blocktype icons continue to work, thumb.png icons in the base directory
    will still be displayed if no icon is found in the raw theme.
