Use correct field separator in keywords.txt 
The Arduino IDE requires the use of a single true tab separator between the keyword name and identifier. When spaces are used rather than a true tab the keyword is not highlighted.

761f4f4fb9 Fixes #81 "signal already there" != "timeout" 
If expectPulse(LOW) sees the port is already LOW (result == 0), this is not timeout!

16e61f1084 Modified read speed 
Reduced delay times from 250ms and 20ms to 1ms.  This was done in accordance with the datasheet.  E.G. no where does it say you need to wait 250ms or 20ms.  It does say to set the line high for a minimum of 1ms (the second delay).  This has been tested and is working in my of my projects

5bc0a5c796 Divisions turned into multiplications 
As correctly stated by Mausy5043, the division is quite slow in most
microcontrollers, so I have replaced them with multiplications.

36fb16274b DHT::computeHeatIndex has been modified so it uses both Rothfusz and 
Steadman's equations. As a result, it allows a larger range of
temperatures and more accurate results for extreme conditions.

f9c3f323e3 Use INPUT_PULLUP 
Previously, the mode was configured to INPUT and then written HIGH,
which works on AVR but isn't very portable. Instead, this uses the
INPUT_PULLUP pin mode (available since Arduino 1.0.1) which is portable.

45a20da301 Shrink DHT::data to 5 bytes 
There's only 5 bytes of data being transferred (2x2 bytes of data, 1
byte checksum), so no need to keep a useless byte.

5973929e63 Remove the firstreading variable 
By cleverly setting _lastreadtime in begin() to make sure that it looks
like the last read was alrady 2000 ms ago, even on startup when millis()
still returns 0, there is no longer a need to keep a separate
firstreading variable, saving a byte of memory and a bit of code.

f1b79028ea Clean up two-second interval check 
There was some handling of millis() overflow that is not needed.
Standard unsigned subtraction and wraparound already works as expected,
so this extra check can be removed (it even hurts, since it introduces 2
seconds after a wraparound where no new data will be read, even if it
could otherwise happen).

Also, this prevents calling millis() a second time, since its value is
already known.

04905bc5cd Add force parameter to read methods 
This allows forcing a read, even if the previous read was less than 2
seconds ago. This is useful in cases where the millis() timer is not
reliable, such as when sleeping. In this case, it is up to the caller to
ensure that at least 2 seconds elapse between calls with force set to
true.
