Updated the driver 

Updated the driver and changed a lot. 
- Starting with switch(function) and the end of it. 
- Changed the json output code a lot to more visibility and a better way of working. 
- Changed the web sever outout so that we need less code.

In #ifdef USE_DOMOTICZ i have changed nothing because i don't have a domotica system.
Therefor someone with a stable running system can build it further or we can work together on it.

Dirver version changed to v1.0.0.2
Theo, i hope the if (11 == (uptime %100)) { .. part is ok. Please have a look on it.

Version Date Action Description
--------------------------------------------------------------------------------------------
1.0.0.2 20180928 tests - same as in version 1.0.0.1
cleaned - source code
changed - snprintf_P for json and web server output
- much more compressed and more professional code
added - uv_risk_text to json and web server output
changed - switch (function) to be 100% compatible
- added Veml6070EverySecond in thought of compatibile
added - Veml6070UvTableInit to do this only once to spare time
debugging - @Adrian helped me out in case of a %s%s in mqtt_data. Thank You Adrian
next - possible i will add the calculation for LAT and LONG coordinates for much more precission (TBD)
- show not only the UV Power value in W/m2, possible a @define value to show it as joule value (TBD)
- add a #define to select how many characters are shown benhind the decimal point for the UV Index (TBD)
---
1.0.0.1 20180925 tests - all tests are done with 1x sonoff sv, 2x Wemos D1 (not the mini)
- 3 different VEMl6070 sensors from 3 different online shops
- all the last three test where good and all looks working so far
