/sudo, /timecmd
Fixed the regex in /sudo to ignore the first / if it exists.

Added /timecmd, which is a way of delaying commands. The syntax is /timecmd [-switches...] <time> <command...>, with <time> in _d_h_m_s format, and the -repeat switch can be used to indefinitely repeat. /cancel can be used to stop the time command prematurely.
