Label-Field restricted to 20 Characters

[sls83]

Hello Daniele,

first of all, thank you for your fork of webvirtmanager.
We are using this tool since about 1 Month with no problems.

Now we have changed our DNS-scheme, which means longer Instance-names.
The Problem is now with the ACL-Gui (Django-Adminstration).
If we want to safe an ACL for a specific Instance, it can`t be saved. Because the Name-Field of the Instance is restricted to 20 characters in this GUI. But our Names are longer than 20 chars.
Can this Field-length be extended? To 255 Chars maybe?

Thank you for your help!
Best regards,
Stefan

Thanks for your feedback, and I'm sorry for the long waiting response, but I've been busy. Your suggestion looks a good one, I will have a look to this issue and I will try to extend the fields.
I will try to open a PR to the original project first; if we don't get it merged in reasonable time I will put it directly into my codebase.
