#740 FAQ: more wiki features in FAQs

[Van Woods]

The FAQs would be much more useful if they were similar
in nature to the rest of Tiki's wiki features.

(items with * are most important)

Specifically I would like to see the following options
appear as tabs like in the wikis:

edit
remove
rename
lock
perms
*history
similar
export
comment
translation

And, I would also like to see the icons that appear on
the wikis:

edit
backlinks
3d browser
*print
*create pdf
