SystemMonitor: Use size_t for graph values

Browse source 
The memory and CPU graphs fail to display anything when the memory size
is larger than 2**31 bytes, because of the small range of int. This
commit makes replaces the type with size_t. Hopefully nobody will have
18 quintillion bytes of memory before this gets replaced. :^)
