Sanitize tabs

[seezee]

In order to pass PHPCS, I've changed the following lines in Class _Settings:

334:	$current_section = $_POST['tab'];
	$current_section = sanitize_text_field( wp_unslash( $_POST['tab'] ) );
337:	$current_section = $_GET['tab'];
	$current_section = sanitize_text_field( wp_unslash( $_GET['tab'] ) );
409:	$tab .= $_GET['tab'];
	$tab .= sanitize_text_field( wp_unslash( $_GET['tab'] ) );

These fields should never contain HTML anyway so this seems a good way to handle this unless there's some edge case I haven't thought of.

I would open a pull request, but I'm still learning how to use version control and haven't figured out how to do that yet :-(

@seezee would you like me to record a screencast, on how to create a PR, might be a useful learning experience for you?

That would be awesome!
