Updated Icon's icon list to match current Font-Awesome list
Changed the way Tables are constructed
Tables now use three arrays (head, foot, body) to construct their
children.  Older style syntax (using children) is still supported, but
will be phased out soon.
Removed Nav's override of List's default childPrefix/Suffix, this allows
for custom prefixes/suffixes to be used with Navs
Bumped version to 0.6.2
