Remove global reset in favour of contextual reset.

Rather than having a partial reset with individual elements having
their styles built back up, only elements without replacement
styles have specific properties 'reset'.

This commit also includes: a correction to the font mixin arguments
used on forms (the output is now valid CSS); the removal of
`overflow-y:scroll` from the `html` element which is now known to
cause some problems for jQuery modal plugins in Firefox.
