Set timeouts to avoid Slowloris attacks.

[mmjunior23]

It would be nice to set timeouts to avoid Slowloris attacks.
Something like the following:

$ dhttpd --IdleTimeout=30 --ReadTimeout=10 --WriteTimeout=10

-it, --IdleTimeout=<seconds>    Closes a connection if no data is requested before the timeout interval. (defaults to "30")
-rt, --ReadTimeout=<seconds>    How long the server waits before it closes a connection when it is waiting for an HTTP read request to complete. (defaults to "90")
-wt, --WriteTimeout=<seconds>   How long the server waits before it closes a connection when it is receiving data from client. (defaults to "120")
