webui: Allow full search on devices page (#8364)

* Update devices.inc.php

* Update devices.inc.php

* Replace $_POST with $vars

Better protection for SQL injection attempts; Need to verify other files for same issue.

* Fixed whitespace.

*sigh*

* More search options & sql injection fixes.

+Allow full search on devices page;
+Allow sysName search on alertlog page;
+Allow sysName search on alerts page;
+Allow sysName search on eventlog page;
+Allow sysName search on poll-log page;
+Allow sysName search on ports page;

*Replaced all occurrences of $_POST with $vars in librenms/html/includes/table. ($vars are sanity-checked).

* Whitespace fix

* Fixed $where & $param

* Add files via upload

* Whitespaces....

Sometimes you want'em, sometimes you hate'em.
