install of KCE fails if you install in on /

for example: create a new vhost on your server - eg. kaltura.bouncingminds.com

when you install the install fails - no clear reason is displayed. The reason is that the $server_root is "" and when

install/run_replace_root.php

is called the following line of code executes

from ----- install/run_replace_root.php ----

if (!$server_root)
{
echo 'must have server root as argument';
exit(4);
}
-----

recommend simply removing the exit (4) line

when I press submit nothing happens - I keep seeing the same submit form
