Hello World demo for Enhanced TextLCD lib.
The Enhanced TextLCD lib supports more display types than the original lib. Added support for User Defined Characters (UDCs), Backlight control and other features such as control through I2C and SPI port expanders and controllers with native I2C and SPI interfaces. See here for more info.

- Commit message:
- Hello World demo of Enhanced TextLCD library. This lib supports HD44780 based controllers using 4bit parallel bus on mbed pins, I2C or SPI expanders. The libs also supports native I2C or SPI interfaces on several HD44780 compatible controllers.
