MINOR: hlua_fcn: add Patref:add()

Browse Source 
Just like "add map" and "add acl" on the cli, the Patref:add() method can
be used to add a new entry to the pattern reference pointed to by the
Lua Patref object. The update will target the live pattern reference
version, unless Patref:prepare() is ongoing.
