Improvements to User and Permission models

[Bastian Kleineidam <calvin@…>]

The Permission model increases the maximal permission name length
from 50 to 100 (I actually hit this limit with some model permission
names some of my projects).
The User model will be sorted by last name, first name and then
username. And the string representation of a user will include the
last and first name if defined.

These are two unrelated changes, so should really have been two tickets.

The Permissions one would be nice to have, but is backwards incompatible, so we need to judge the right moment to include it. Shouldn't be too harmful, though, and can be included in the list of database changes required to go from 0.96 to 1.0.

The User changes are a little less clear. The extra ordering is very much personal preference and adds a small performance hit. I don't see a huge need for that. Similarly, the string format change is a bit "take it or leave it" -- again, some people want one thing, others are going to want something else. Probably not worth changing just so that things continue to display as they always have. There are very few cases where you're going to be forced to use Django's version of the string format and cannot replace it with your own if you want (admin might be one place, but we have to make a trade-off in those cases).

So, I'm +1 on the Permissions changes and -1 or -0 on the User changes at the moment, at a first impression.
