URL aliases form limits fields to 1/2 their defined/DB size

The admin/build/path/add page limits both the "Existing system path" and the "Path alias" entry fields to 64 characters but the src and dst DB columns have 128 character capacity.

In path.admin.inc, changing
'#maxlength' => 64
to
'#maxlength' => 128
for both $form['src'] and $form['dst'] appears to fix these issues.
