Add size/alignment controls for standard excerpt images

[postmastersteve]

When a P6 site uses the standard excerpt appearance for a blog page type, and when large images are used, the photos will only expand to 100% of their original size.

When the browser is wide enough that the image does not fill the content width, the image is positioned left-aligned at 100% size, but does not fill the width.

Consider providing one or both of these controls in the Content > Excerpts area:

• up-scale images to fill the width of the content area
• center images at 100% max image size

Currently, we provide users with CSS code for each of those options:

.article-content .excerpt-image-fullsize img {
    width: 100% !important;
    height: auto;
}

article.excerpt .excerpt-image-fullsize {
    text-align: center;
}

It seems like we could easily offer a settings box so users could choose this behavior themselves.
