Work in progress for artin reps
Reorganizing artin representation home pages, putting dynamic group knowls in artin rep search table, and updating which artin rep database table we use.
Fixed the line:

        self.Q_fe = self.Q_fe = float(sqrt(Integer(self.conductor))/2.**len(self.nu_fe)/pi**(len(self.mu_fe)/2.+len(self.nu_fe)))

by changing the divisions by 2 to division by 2. (i.e. floating point).
Integer division returns an int and so, for odd len(self.mu_fe), the
above was producing wrong powers of pi.
Add citation link at bottom of every page.
