v0.02

* Cleaned up the code for readability

* Added routines to display RAM info on the LCD

* Added routines to display SWAP info on the LCD

* Added routines to display the different CPU states (user, system, idle and nice) on the LCD. TODO: make it only count the CPU states for the last period of time (how many seconds???), at this point it shows the total time of each state since reboot != good.
