* Bradley Jarvis (bradley.jarvis@dcsi.net.au)
* Lukas Zvonar (lukic@mag-net.sk)
* Petr Zitny (petr@zitny.net)
* Alexey Ozerov (alexey@ozerov.de)
* 2011-12-20 some code cleaning and restructure, read_period, km/h wind speed
* 2011-12-21 introduce ws_parse(), struct wrecord
* 2011-12-22 flexible read period, server url, curl post data
* 2011-12-25 add inches, mph, utc, introduce ws_format(), urlencode, additional url
* 2011-12-26 readd rain 60 min calculation
* 2011-12-28 read config vars from cfg file, multiple add_url, date DD.MM.YYYY and time HH:MM formats
* 2011-12-29 read read_period from WS, add rain from 0h calculation
* 2012-01-01 fix error handling in main(), handle ws_submit feedback, get lasttime, submit multiple positions, submit error
* 2012-01-02 submit last error text to frewe-server
* 2012-01-03 add support for wetter.com, more accurate time calculation for position shift, accurate cfg read
* 2012-01-05 don't encode : in HH:MM
* 2012-01-05 rewrite read_cfg(), add station type, support WH3080, calibration, read data_count
* 2012-01-08 check data_count when looking for old records, plausi check for age, read illumination & UV
* 2012-01-14 Better check for invalid values, skip record if too many errors, fix rain calibration
* 2012-01-15 Double read the data from USB device
* 2012-01-16 Fix time calculation for submission to frewe-server
* 2012-01-19 Fix linebreak after OK problem on frewe-server responce
* 2012-01-24 Integrate weather service URLs, fix bad data prevents position loop problem
* 2012-01-25 Read weather service access data from cfg
* 2012-01-26 No formatting in ws_parse, different errorstrings for different services
* 2012-01-27 Fix address calculation on address overflow
* 2012-01-28 Handle signals, fix ws_close(), fix address calculation again, multiple tries on USB read problems, recognize sensor loss, station type %K
* 2012-01-28 Don't handle SIGHUP
* 2012-02-01 Use http_fetcher instead of curl (saves 200 KB, however is not IPv6 capable)
* 2012-02-03 Resubmit data also to known weather services
* 2012-02-04 Handle DOS encoded lines in cfg file, read alarm config, introduce ws_alarm, clean up some code
* 2012-02-05 Configure emails for errors and alarms in cfg file, enable multiple alarms of each type, fix memory in URLencode
* 2012-02-09 Fix UV value output
* 2012-02-11 Add Sauerlandwetter
* 2012-02-23 Don't drop record if sensors are lost, NB: total rain, indoor values and abs. pressure (?) are usable even if sensors are lost
info: frewe.ws_dump - 0xD6C0: 0x05 0x38 0xEE 0x00 0xFF 0xFF 0xFF 0xEE 0x27 0xFF 0xFF 0xFF 0x8C 0x6B 0x03 0x40

* 2012-02-24 Only resend data to services which support it, don't resend if sensor lost (sensor lost = good data)
* 2012-03-06 Handle HighIndoorTemp and LowIndoorTemp Alarms
* 2012-04-04 Continue sending to other weather services on error
* 2012-05-24 Don't run out of available data on rain calculation
* 2012-06-11 Flush the stdout (enable data logging into a file), use stderr for debug and info output, wetter.com replaced wetter.de
* 2012-06-13 Include age of last record last_age in record datetime, pos60 and pos0h calculation, fix rainday calculation for old records
* 2012-06-15 Ignore get lasttime errors if frewe-server is not available
* 2012-07-27 make unit conversions in ws_format() instead of ws_parse()
* 2012-07-27 WH3080: Transmit illumination in W/m² instead of Lux to WUnderground, PWS, Awekas, METOffice
* 2012-09-01 Remove Wetterpool.de, add Wetternetz Sachsen
* 2013-03-16 Remove Sauerlandwetter, rename time_interval to read_period, increase http timeout to 15 sec, print version info with -H

* 2013-04-11 Fix SIGSERV by getlasttime from wrong input, fix pause calculation (int overflow)
* 2013-04-25 Fix pause calculation again
* 2013-05-23 Fix pause calculation again (use usleep), use getaddrinfo in http_fetcher.c, better validation rainday and rainhour
* 2013-06-22 Trying to fix stability issue when FreweServer fails, ignore FreweServer submission fault
* 2013-07-01 Fix stability issue within logger function (use strcpy instead of strcat)
* 2013-07-12 Try resetting USB port on errno 62 when setting alt device
* 2013-10-13 New interface URL for Wetternetz Sachsen (2.1)
* 2014-08-10 Add fhem file
* 2015-03-25 Send UTC time to frewe-server
* 2015-04-24 Handle lasttime as UTC
* 2015-08-20 Don't write fhem.txt for older records
* 2016-01-16 Separate read interval for fhem.txt, run each 48 seconds for FHEM
