Link-Distance!!!

Changes:
- Config option: form_position is renamed to links_form_position.

Bugfixes:
- install.php: the changes made by 0.2->0.3 upgrade also made in the install script.
- email verification code fine-tuned
- added ldr_php4.php for PHP 4.x compatibility

New Features:
- New config option: links_form_position: the old form_position
is moved to a new section: links. It also has a new option: none.
- New config option: form_select_category: if set the addlink form has a
drop-down menu to select category.
- Link-distance check (experimental): now the reciprocal_max_link_distance option is active.
By default it is set to 1. Be very careful if you want to change it to a higher
value, it can take a lot of time to check new links and it can take lot of
memory on your server.
