Fix issue #2396

install.php respect useacl=0 choice

use absolute URL in index.php when redirecting to doku.php

fix Windows tests for #2702

Currently DOKU_INC, DOKU_CONF in test bootstrap is not consistent with our `fullpath()`, causing the concatenated expected string in styleutils_cssstyleini_test not correct in Windows; this patch use str_replace to turn Windows separator into Linux ones.

Note that in order to get an absolute URL, the whole DokuWiki environment is loaded now in index.php.
