Vesrion IAP with LPC11U24_EEPROM_ONLY options

Fork of IAP by Tedd OKANO

This is IAP library from http://mbed.org/users/okano/notebook/iap-in-application-programming-internal-flash-eras/ Added option LPC11U24_EEPROM_ONLY in IAP.h that disable flash write/read functions if they not needed and working only EEPROM write/read functions. It make for clear memory allocation for flash write functions (4k).
