Major updates:

- added DAConverter(s) - added ADConverter(s) - Fixed some display issues - Made repair process and signalProfileGenerator calculate with voltages (signed) instead of DAC/ADC values - Fixed several bugs in task handlings - Put display data mirror into dedicated file displaycontent git-svn-id: https://svn.vbchaos.nl/svn/hsb/trunk@261 05563f52-14a8-4384-a975-3d1654cca0fa
