Lots of keys are being added to the postmeta table

Right now, there's a key/value for every hrld link in the format.

key: hrld-inline-$url
value: int (click count)

This is because there can be multiple inline links in any given post.

This is not ideal for sql, since there's an index on the key field. We should limit the number of keys being generated by making the key/value pair:

key: hrld-inline
value: array( "url1" => count1 , "url2" => count2 ... ) (serialized array)

Of course we'd have to write a script to alter the current database values.
