readTempC does not wait until TB in status register is cleared

[GoogleCodeExporter]

The readTempC() function now does a delay(20) after requesting a new 
temperature. Accorfing to the datasheet one should wait until the TB flag is 
cleared in the status register.

see discussion @ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1289330809/0

[code]
  // wait until TB register clears, see page 15/29 datasheet
  // iso delay(20);
  boolean ready = false;
  while (!ready)
  {
     //copy data from eeprom to scratchpad & read scratchpad
    _readMem(_scratchPad);
    ready = ( _scratchPad[STATUS]  & 0x10) == 0x00;
    delay(10);  // wait before reread of the scratchpad
  }
  // TB is cleared so conversion is ready
[/code]

Same is possibly true for the other readings, did not look after that.
