mandoc: Switch the emitted HTML element from <b> to <code> for the fixed

[schwarze@mandoc.bsd.lv]

Log Message:
-----------
Switch the emitted HTML element from <b> to <code> for the fixed 
syntax element macros .Nm, .Fl, .Cm, .Ic, .In, .Fd, .Fn, and .Cd.
Adjust both the internal and external style sheets such that 
rendering remains unchanged in typical browsers.

Based on feedback from John Gardner <gardnerjohng at gmail dot com>.
