double accusative with clitic

[olzama]

Commit 030b17e divorced and re-constrained LOCAL.AGR and HOOK.INDEX in pronouns and clitics. Result: overall improvement (less overgeneration), but lost parses for the double-direct object ("La gata, la conozco"). The parses were not fully correct before (the clitic was dangling unattached in the MRS), but perhaps it was not so bad to have them. I suspect that an additional lexical rule is needed for such sentences, one that explicitly assumes a double direct object expressed as a clitic.
