Fixes Compile warnings and Adds Panic and Compile time and runtime controlled Debugging

This adds Debug logging and Panic features.

```cpp
/*
 * This module supports runtime and compile time message filtering.
 *
 * For a message be compiled in the message type has to be >= to then the LOG_LEVEL_AT_COMPILE_TIME
 * For a message to be output the message type has to be >= then the LOG_LEVEL_AT_RUN_TIME
 *
 * This module assumes one of two #defines RELEASE_BUILD or DEBUG_BUILD exist
 * Then the LOG_LEVEL_AT_COMPILE_TIME and LOG_LEVEL_AT_RUN_TIME are set based on RELEASE or DEBUG
 * For a release build
 *     LOG_LEVEL_AT_COMPILE_TIME = WARN_LEVEL
 *         LOG_LEVEL_AT_RUN_TIME = WARN_LEVEL
 * For a debug build:
 *     LOG_LEVEL_AT_COMPILE_TIME = LOG_LEVEL
 *     LOG_LEVEL_AT_RUN_TIME = LOG_LEVEL
 * The API
 * LOG(fmt,...)
 * DEBUG(fmt,...)
 * WARN(fmt,...)
 * ERROR(fmt,...)
 * PANIC(code,fmt,...)
 */
```
Usage:
```cpp
define DEBUG_BUILD=y on make command line and add the following to your Application.cpp

void debug_output_(const char *p)
{
  static boolean once = false;
 if (!once)
   {
     once = true;
     Serial1.begin(115200);
   }

 Serial1.print(p);
}
The API looks like

LOG("Want %d more cores",count);
WARN("Running %s on cores only %d more left",,"Low",count);
DEBUG("connection closed %d",retValue);
ERROR("Flash write Failed @0x%0x",badd_address);
PANIC(HardFault,"Hit Hardfault");
```
Panic codes are defined in panic_codes.h

PANIC(code,[text])
```cpp
// Add a panic code def_panic_codes(_class, led, code)
// the panic module will send SOS followed by 900 ms delay
// followed by 300 blinks of the value of code
/// ...---...    code   ...---...

This is added to the while(1) loop in the code to help identify a Fault or Fault condition
Currently used

def_panic_codes(Faults,RGB_COLOR_RED,HardFault)      1 blink
def_panic_codes(Faults,RGB_COLOR_RED,NMIFault)        2 etc....
def_panic_codes(Faults,RGB_COLOR_RED,MemManage)
def_panic_codes(Faults,RGB_COLOR_RED,BusFault)
def_panic_codes(Faults,RGB_COLOR_RED,UsageFault)

def_panic_codes(Cloud,RGB_COLOR_RED,InvalidLenth)

def_panic_codes(System,RGB_COLOR_RED,Exit)
def_panic_codes(System,RGB_COLOR_RED,OutOfHeap)
