Introducing changes proposed to chan_unistim driver:

1) Added the unistim.conf variable dtmf_duration which can select the DTMF playback duration from 0ms to 150ms (0 is off and is the new default)
2) Enabled the transmission of month names, which are sent with the date and changed the dateformat variable to accept the values 0-3 as per the UNISTIM standard (2 & 3 match the previous 1 & 2 formats).
3) Enabled the "Mute" packet so muting microphone works as expected and microphone muted for all calls while LED light on
4) Changed Duree to Timer on i2004 display

(closes issue ASTERISK-23592)

+ * Added option 'dtmf_duration' allowing playback time of DTMF tones to be set

+ * Modified option 'date_format' to allow options to display date in 31Jan and Jan31
