mbed-src updated for BMD-200 evaluation board. Just pin numbers are updated.

Fork of mbed-src by
Replacement for the "mbed" or "mbed-src" library when using the BMD-200 Evaluation kit. This library only remaps the pin names (i.e. LED1 points to p0.01 instead of p0.18, etc) as used by the BMD-200 Evaluation board (select the nRF51822_mkit platform). All other code is untouched.

1. timestamp_t as an abstraction for time values managed by
Ticker. Using uint64_t for timestamp_t allows a wraparound-free
Ticker. This change forces us to update the definitions of usTicker
for all platforms; but the changes beyond nRF51822 aren't major.
2. reduce power consumption on the nRF51822 by removing the need for
the high-frequency processor timer; and reimplementing it using the
RTC.
I've also replaced high-frequency clock with low-frequency external
clock during system startup of the nRF51822. This brings a major win
in power consumption.
