options.php double-encodes entities, messing up the data on save

[MC_incubus]

When using the "secret" options.php method to access all options, entities are double-encoded, so for links_recently_updated_append et al, they are messed up on save.

They are already being run through wp_specialchars() but then are run through htmlentities(). My patch removes the run through htmlentities() and it appears to fix it!
