binary data send function debug

modified SAT_AppStorage :
- function send(byte*) : "end" argument renamed "length" to be less
ambiguous
- function send(byte*) : loop was bugged, sending the same data
repeatedly, modified to do the same as send(char*) do
SAT_Accel example

placed SAT_Accel_Example.ino within a directory "SAT_Accel_Example" to
be accessible through Arduino IDE
obtaining raw sensor values

added some getRawData() functions to get the raw (int16_t) sensor values
with no software post-processing (transforming temp into floats with
sensibility etc).
