corrupt EEPROM data

[swede89]

Occasionaly, EEPROM data is corrupt. Each config element should be checked for validity and set to a default value in case of error.

[swede89]

Proposed solution:
Add another check in checkConfig(boolean init) for each config element
BEFORE:
int tempInt = atoi(config.c1);
if (validConfig.c1 != tempInt and tempInt > 0 and tempInt <= 256)
 {
  validConfig.c1 = tempInt;
  changeColor = true;
  Serial.println("Color 1 changed");  
}

AFTER
int tempInt = atoi(config.c1);
if (tempInt > 0 and tempInt <= 256)
 {
if(validConfig.c1 != tempInt)
{
  validConfig.c1 = tempInt;
  changeColor = true;
  Serial.println("Color 1 changed");  
}
}
else if(init) //that means the current EEPROM value is out of bounds and it is not due to user input (as checkConfig was triggered by setup() method with init=true). The condition init can also be left apart causing every misinput to set the EEPROM.
{
Serial.println("Reset c1");
itoa(validConfig.c1, config.c1, 10)
}
