miniupnpd: Updated to latest Git snapshot (resolve PCP issue present in the 1.9 release)
webui: the new USB handling code bases its port count on rc_support - add an extra port to the RT-N66U, for its internal SD card reader
Updated documentation
samba36: Try finding the account without mangling it in any way at first, otherwise mixed-caps names will never be found at all by Get_pwnam()

This resolve issues happening if the router admin user was replaced by one with uppercase characters in it.  Samba would
only try all lower and all upper-case usernames.  Then it could try winning the lottery by randomly attempting
various combinations of cases, up to "username level" attempts.  Since randomly trying such names sound silly at
best, I am simply telling Samba to first try the original, unmodified username.  Then, it can try all upper and
all lower.
