Internal Server Error when duplicate options in LXC config file (With is legal in LXC)

[rkkoszewski]

Hi,
Seems like this version of LXC-Web-Panel doesn't support having duplicate keys in the LXC config file. Having duplicate keys are completely legal in LXC and all options are read properly (Even if duplicate).

One frequent case is when you want to mount multiple things, you're repeatedly using "lxc.mount.entry".

But right now if you have multiple mount points in the LXC configuration, the whole LXC-Web-Panel breaks after logging in.

The exception says:

You are right, have you fixed this?

I think I did by replacing configparser library with another, but not sure yet.
