Allow some HTML for motto and phase names

[mbohal]

Some minor feature issue that I would like to report:

• The page "motto" and phase names sometimes would require better hyphenation or line breaks. The automatic hyphenation in browsers sometimes creates grammatically wrong breaks in words. HTML has entities for that, e.g. the &hyp; to make breaking suggestions. Unfortunately the entities are displayed as plain text (also unicode characters) – any suggestion how we to make it possible?
• We have gotten requests to allow
  or bold / italics /underline also in the page "motto". Maybe it's the same case like the one explained before.

I'm aware that this may increase the risk that admin users break the design or layout. That's why I would like to restrict it to HTML entities and only the four formating aspects mentioned in point 2.

This issue is not urgent, but a task for whenever resources are free. If the implementation takes more than two hours, I would need an information beforehand.

Input in admin will remain as type="text" a note will be added to indicate what HTML tags are allowed.
