Add support for FGCom multiple radio support

Browse source 
PTT now uses an int channel number (0 means not pressed, 1 = comm radio 1 (index [0]),etc...)

/comm-radio-selected is the default comm channel to use. This should usually be the same as will be set by PTT into /controls/radios/comm-ptt

However PTT will switch the FG comm inbound and outbound frequency to whichever radio was PTT'd.

New properties also set in multi-player to indicate the transmission frequency and normalised power (currently just set to 1.0)

13001(int)        : sim/multiplay/comm-transmit-frequency-hz
13002(short-norm) : sim/multiplay/comm-transmit-power-norm
