Twenty Ten editor styles for strong and b elements override user-chosen font colors

[lancewillett]

To repeat: Create a post, choose Visual editor, and use the font color menu to change to color of a word. Then make it bold. The word stays black.

If you undo the bold, then enable it again, the font color works as expected. But we should avoid using colors for visual editor elements to avoid conflicts with user-chosen styles.

To fix: Remove color declarations for strong and b from editor-style.css.

Patch to remove color rules for strong and b elements

After further research on this -- it's actually not a stylesheet issue, it's related to how TinyMCE works, specifically with how it wraps elements with a span element when applying inline styles.

So we can close this as wontfix, and explain that to enable the correct coloring via tinyMCE use this process:

1. Highlight word, select color.
2. Highlight word again, make it bold.
