Add support for static ttf fonts files .

[miky2k]

I supose it's only nedded to add a line here:

static String getContentType(const String& path) {
if (path.endsWith(".html")) return "text/html";
else if (path.endsWith(".htm")) return "text/html";
else if (path.endsWith(".css")) return "text/css";
else if (path.endsWith(".txt")) return "text/plain";
else if (path.endsWith(".js")) return "application/javascript";
else if (path.endsWith(".png")) return "image/png";
else if (path.endsWith(".gif")) return "image/gif";
else if (path.endsWith(".jpg")) return "image/jpeg";
else if (path.endsWith(".ico")) return "image/x-icon";
else if (path.endsWith(".svg")) return "image/svg+xml";
else if (path.endsWith(".xml")) return "text/xml";
else if (path.endsWith(".pdf")) return "application/pdf";
else if (path.endsWith(".zip")) return "application/zip";
else if (path.endsWith(".ttf")) return "font/ttf";
else if(path.endsWith(".gz")) return "application/x-gzip";
return "application/octet-stream";
}

The line added worksforme!

correct it's there ;)
I added font/woff and font/woff2 for bootstrap in my code also

I strongly recommend activate browser caching for SPIFFS to avoid requesting font each time
server.serveStatic("/", SPIFFS, "/", "max-age=86400");
