Add support for a remote NCID server for caller ID

[rudybrian]

The current NCID implementation only supports reading logs from a local NCID server, and doesn't have the full set of features possible with a modem directly connected to (and managed by) MH.

I propose adding support to Telephony_Interface.pm to allow use of a remote NCID server.

The first commit seems to be working, but is still a bit rough around the edges.

To use this, I have the following entries in mh.private.ini:

callerid_port = localhost:3333
callerid_name = acheron-ncid
callerid_type = ncid

I have modified the regex used for type ncid to work with the current NCID format. At some point it changed from

CID:*DATE*10202003*TIME*0019*NMBR*2125551212*MESG*NONE*NAME*INFORMATION*

to

CID: *DATE*03272014*TIME*1734*LINE*1234*NMBR*2125551212*MESG*NONE*NAME*OUT-OF-AREA*

This change should also allow code/public/callerid_ncid.pl to work again even though it is now functionally redundant.

I added some logic in the last commit that will allow MH to reconnect to an NCID server if connectivity is interrupted.

This seems to be working well on my test system, and I would welcome some testing/recommendations prior to submitting a pull request.
