Updated Call Event handling/display for all decoders and updated channel display values for all decoders.

- Call events now show start-stop timestamps.  (or START-In Progress if call is ongoing )
 - Call start/stop events are now on the same event line.
 - Channel panels now display site and/or channel info
 - LTR call events are limited to CALLs on the current LCN, in order to cut down on false call events resulting from noise.
 - Passport display channels now show site/channel.
 - Changed default window used by the DFTProcessor to Cosine, which doesn't have as much FFT bin leakage.
