Read information from memory/swap and CPU

Browse Source 
This commit is the second of an incremental serie. There will be other
commits with the information about tasks and the support for BSD and
Solaris once things are settled.

The TaskManager class is build with a new source task-manager-linux.c
that provides functions specific to the Linux implementation. It has
functions to read the usage of the memory/swap and the CPU.
