Apply label styles to default label too

This changes allow for properties in the main textLabel and detailTextLabel to be set from the styles hash in each cell.

This was possible to do with attributed strings but I think this is easier for some common attributes.

I added the code where I thought made more sense, but as line 11 says, this file probably needs some deeper house cleaning :)

PD: pulling to edge now, sorry, should have RTFM :)
