* Use string derived from serverDescription for wifi.hostname()
The code was sending illegal hostname strings to WiFi.hostname() (which is then submitted to DHCP and often times to DNS.) A valid hostname contains only alphanumeric characters and hyphens (though it can't start with a hypen.) This change simply alters the value passed to wifi.hostname() by replacing all non alphanum chars with hyphens while ensuring the first char is never a hyphen. If the resulting hostname is empty, it uses the escapedMac value (which I'm assuming is initialized by the time this code executes.)
This change would result issue #1033
* replace string with char array
prefix wled
