Bold in figcaption

Opted to make bold a white color. Could not figure out how to target
only first occurrence of a bold tag ONLY if it started the caption. As
a workaround, going to treat all bold/strong as the same. Closes #202.
Normalized outline value.

Now “0” instead of “none”.
Remove dotted outline from images

Closes #201.
