First commit of Light Log device firmware using PICAXE-08M2.
Switch to PICAXE-14M2, 64Kb I2C eprom, and 10bit sensor readings.
Fixed (maybe) bugs with for loops near max int.
Added code to help debug eprom reads and writes.
Code refactor removing main for loop.
Continue at last record after reboot, sensor VCC to C.4 powering off between samples.
Power, sampling, serial comms & flag changes.

Improved avarages (no roll over between saved samples, more accurate)
Added dump data and continue test routine
Added serial cmd commands
Dropped to 2Mhz = serial 2400bps (any slower seems to make serial io flakey)
Replaced 255,255,255,255 reboot with extra_byte 2-bit flag in data
High speed erase (should do this for data sync next)
Fixed i2c fault at higher than 8Mhz clock speeds & log data now dumped at 38400 baud.
Raw binary data sync, improved power saving, reduced sample rate, client commands added.
Testing for back reflection using LED blink & Hello? ping for auto serial sync.
Improvements to light block testing and behaviour.
Don't flash led when getting status (looks like a reboot).
Code refactor and added firmware version to device status output.
**** HARDWARE v0.5 RED FLAG incompatibility *****

C.1 for LED output
C.0 for Clear LDR input
C.3 for Button
Improved debugging output options
Tuning for blocked sensor detection (linked to new enclosure design).
Sensor blocked refactoring.
