Avatar and Categories

[Arthens]

When you have just few avatars it's ok the have them listed, but if you have a lot of avatar it's going to be a mess.
IMHO it'd be useful to have the possibility to create different categories of avatars.

It could be done using a directory for each category (so you don't have to write an interface for add categories), if you want to add a new category you just have to create a new directory and upload the avatars there.

And it'd be even greater if, when the user selects the avatar, all the categories but the default would be collapsed, like
Category Name ---------------------------------
Category 2 Name ------------------------------
And you have to click on them to show the avatars.

IMHO choose the category and then the avatar is better than to have to look at a lot of avatars with different subjects.

By this way you could also consider to drop the possibility of hiding a single avatar (is really useful?)
A category based permission system would be more useful (for example you could add a set of avatar just for one group) and would save you a lot of permission check (If you have 1000 users with they own avatar you are going to check 1000 times the permission every time you change the avatar)

As a first step I added paging for avatars on both the users and the admins view (see #17)
