Fix for elliptic curve L-function plots

Elliptic curve L-function plots were broken for large conductor because
I had previously "optimized" plotting by precomputing the plot data. The
database I created with a larger number of plots had a slightly
different format than the small database I had created.

The database on the server will need to be switched to the larger one
before plots actually appear, but the code should work with either the
small database or the large one.

Fixed routing for /Character/Dirichlet

I think that at some point someone moved the Dirichlet character routing
from website.py to DirichletCharacter.py. Except that they didn't remove
some routing from website.py, so the new routing wasn't used. Later on
someone came along and removed the extraneous routing in website.py, and
probably didn't check that the website worked after that, because the
routing in website.py was the only correct routing.

This is a small fix to make things work in DirichletCharacter.py.
