Rsapmd user configuration always add header and rewrite subject regardless of SPAM tag method configured
## wrong behaviour
Rsapmd user configuration generated always include `add header` and `rewrite subject` regardless of SPAM tag method configured in ISPConfig spamfilter policy.
## correct behaviour
Rsapmd user configuration generated should include "add header" or/and "rewrite subject" based on SPAM tag method configured in ISPConfig spamfilter policy.
## problem
The problem is causated by the code in `rspamd_plugin::user_settings_update()` from `/server/plugins-available/rspamd_plugin.inc.php`:
```
class rspamd_plugin {
# (...)
function user_settings_update($event_name, $data) {
# (...)
$tpl->setVar('rspamd_spam_tag_method', floatval($policy['rspamd_spam_tag_method']));
# (...)
}
}
```
## proposed fix
`rspamd_spam_tag_method` is a string not a float, so it should be set like this:
```
class rspamd_plugin {
# (...)
function user_settings_update($event_name, $data) {
# (...)
$tpl->setVar('rspamd_spam_tag_method', $policy['rspamd_spam_tag_method']);
# (...)
}
}
```
