IP Geoloc throbber default text issues

Hello,

The "Locating you..." message is displayed randomly on different page loads. I tracked down this to two issues:

1. The ip_geoloc.admin.inc uses filter_xss_admin() function to clean up the saved variable for the throbber text.
This means that if you enter <none>, this will NOT work, because the above mentioned function will remove everything.
You can test this simply by installing Devel, going to devel/php page and executing the following code:

// The output will be NULL. This means that saved value is erased.
dpm(filter_xss_admin('<none>'));
// The output will be <none>.
dpm('<none>');

2. The if statements should be fixed. Here's what I mean:

Now: if ($throbber_text !== '<none>') {
Should be: if ($throbber_text != '<none>') { (only one equation sign).

Patch will be attached shortly.

Let me know if you have any questions.

Thanks you!
