make the "ProxyHTMLFixups" options case insensitive

Hi, 

The "ProxyHTMLFixups" in mod_proxy uses case sensitive string comparison function, i.e., strcmp, which conflicts with the case insensitivity of Apache's configuration design. According to my understanding, httpd champions case insensitivity for both configuration directive and configuration options, e.g., "ProxyHTMLDoctype".

The fix is straightforward as follows:
