Made lat/long int32_t instead of floats for performance and precision
use const char ptr instead of non-const in string literal parameters
rename sketch to match folder
Update Adafruit_GPS.h

Fixed checksum to disable Antenna Messages.
clarified parsing example for MEGA users

following the instructions in the comments while using a MEGA was wrong:
* "comment out the above six lines" - no six lines to comment out.
* mySerial was called on line 83 when requesting firmware version, and would
  not have been instantiated if using just "Adafruit_GPS GPS(&Serial1);"
Added interrupt support

Added interrupt support to shield_sdlog sketch

Fix race condition with calling lastNMEA twice in shield_sd example.
Remove scaling from minute calulcation.

Pull #13 added scaling of minute values by 50 / 3, but this seems to cause problems like minute values going over 60.  Removing this calculation to take the exact minute value given by the module.
