Add more default net types 

Previously Icarus only supported a default net type of wire or none.
This patch adds the rest of the supported net types (all except
uwire and trireg) to the `default_nettype directive. It also fixes
make_implicit_net_() to use the default_nettype instead of always
using implicit (the same as wire).
