Detect RAM usage and stop if full

Browse Source 
This resolves issue #1356 and add the ability for the Arduino IDE to
detect the amount of RAM allocated to a sketch and compare that to the
available RAM on each board. If RAM is more than 90% full, it will fail
on building since there is not enough free RAM for the heap and stack to
use.
