deemphasize less important information; highlight key data

[mattcoarr]

Don't overly emphasize unimportant information (labels, conditions, hierarchy in the stix/cybox document).

For starters:

• change coloring of constraints (condition, etc) from red to gray
• highlight constraints in windows registry key the same as in cybox properties
• remove the border and label around cybox properties and let data stand alone

[mattcoarr]

constraints are now displayed as dark gray: f0afef9457b23d214b661006cc5c01c03ecfdce5

constraints in windows registry objects are now displayed using the same css styles as in cybox properties: e0a47b954ef8ff89b7f7ab18b8410c867840dc5b

make the headers non-bold and the important data elements bold.

this is mainly targeted at:
 * cybox properties (and anything styled similarly)
 * windows registry
