   * Added some power saving features, needs some testing to confirm this is working properly

   - Because conky is written in c (not c++) it can't directly access the system heartbeat timer so it uses another process to do this for it
     + Conky will look for another app I wrote and modified for this purpose, Proximus (>= v1.2.4)
     + If proximus-daemon is running conky will ask it to set up a heartbeat timer and proximus will send a dbus signal back for each heartbeat
     + update_heartbeat_min and update_heartbeat_max from the conf file will specify the approximate time between heartbeats
     + If the phone is discharging, Conky will skip heartbeats according to the value of update_heartbeat_battery_skip in the conf file
     + So, if update_heartbeat_battery_skip is 3, conky will update once every 4 heartbeats when discharging. default is 1 so set to 0 to disable.
     + If the screen turns off, update_skips_when_sleeping overrides update_heartbeat_battery_skip. default is 5!
