Feature: count of members in host groups

[Crazy Marty]

It'd be great if, on the [Configuration]:[Hosts]:[Host Groups] page, a column was added for the counts of members of each group.

Patch

Here attached is a quick patch adding the requested feature: a number of hosts in each hosts group in the group configuration page.

It is sql independant, and i've labelled the header " # ", removing the necessity of adding traduction (yeah, I'm that lazy).

If there is any problems, warn me. This patch was created from version 1.4.0 tree.

Implemented and integrated into 1.4.x.
