don't require install directory to be removed

[sproctor]

instead of requiring the install directory to be removed, we can make the install script inoperable when there is a config.php with content.

The other thing, in setup.php lines from 38 should reflect something like this

if(!defined("PHPC_DEBUG") && file_exists("$phpc_root_path/install.php")) {

echo <<<END
<div class="ui-widget">
    <div class="ui-state-error ui-corner-all" style="padding: 0 .7em;">
        <p><span class="ui-icon ui-icon-alert" style="float: left; margin-right: .3em;"></span>
        <strong>Alert:</strong> You have to remove the install.php file!!</p>
    </div>
</div>
END;
    //display_error(_("You must remove the install script to start using the calendar. If you see this error but you must install the database, goto <a href=\"install.php\">install.php</a>"));
}

No more soft error, but a big alert on top of the calendar.

Must be formatted nicely :D

15 works, but index.php goes in soft error till we don't remove install.php

Brain is apparently mush today. Just committed that fix.
