Version 1.2.1_RC5
Main changes - changes by bperrybap:
- Use LCD_5x8DOTS as default.
- activate backlight in the begin routine.
- minor corrections to the various libraries.
- Fixed incorrect use of 5x10 for default font (now matches original LQ library)
- Fixed typo in SR2W mask define names changed default backlight state to on
- Added support for faster SR_2W mode

+// 2012.03.29  bperrybap - Added delays for faster fio shiftout (it got too fast)
+//             AVR needed delay. cmd/write delays are based on CPU speed so it works on pic32.
+//             Added code to support indicating two wire mode by using enable=data pin
+//             (documentation indicated this as working)
+//             Fixed incorrect use of 5x10 for default font - now matches original LQ library.
+//             can now eliminate enable pin in constructor for two wire mode.
