Added cpu info and vmware host info to inventory

[bsteph]

I created a set of patches to add the following columns to the inventory screen:
CPU Slots
CPU cores
Logical Processors
RAM (MB)
and VM Host

Some software (Oracle, SQL Server, and others) are licensed by CPU slots. For capacity planning, we need to know how many cores are supported and if Hyper-threading is in use (Logical Processors) and how much RAM is installed.

We also find it useful to track which where vm's are running (VMHost) to determine if our VM's are migrating excessively.

I've created a set of userparameters for our Linux machines, and a powershell script that goes out and collects the information and populates the database for our windows machines.

Bsteph, thanks for the patches!

Could be possible to make the same modifications but for the zabbix version 2.2? since there are a few changes in the inventory.php. and I am not an expert in php :/

Thanks in advance!
