Updates for NadHat

[sdoubey]

The goal of these updates is to support NadHat card

I had to add "SIMCOM_Ltd_SIMCOM_SIM800C" configuration and update configurator to load properties file from classpath OR modem folder

I had to fix date parsing for incoming SMS because i got this error, java.time.format.DateTimeParseException: Text '18/08/11,22:36:21+0000' could not be parsed, unparsed text found at index 20, so i had to change yy/MM/dd,HH:mm:ssx to yy/MM/dd,HH:mm:ssX, to support both formats

I had to handle response for SMS larger than 160 characters, when i tried i got this response from CMGSText command:
[+CDS: 6,178,"+33XXXXXXX",145,"18/08/12,00:54:21+08","18/08/12,00:54:21+08",0<R><N><R><N><R><N>+CMGS: 179<R><N><R><N>]
but you are waiting for something like that:
[<R><N>+CMGS: 181<R><N><R><N>OK<R><N>]
so i changed matcher.matches to matcher.find, it's more permissive and does the job

Great job sir.

I do some tests and merge as soon as possible. The NadHat card look very interesting.

Thanks for the contribution :)
