Add support for DS1307 RTC module

Browse Source 
DS1307 does not seem to have the lost lostPower function. So the time does not get set on upload and needs to be set manually as described in the [wiki](https://github.com/sanni/cartreader/wiki/Real%E2%80%90Time-Clock#setting-the-time).

In Config.h set like this:

````
#define RTC_installed
//#define DS3231
#define DS1307
````

Connect "Tiny RTC I2C module" or similar to the SDA/SCL/VCC/GND pins.
