#1304 P25 Phase 1/2 decoder enhancements. (#1898)

Browse Source 
* P25 Phase 2 now supports control channel decoding and decoder was enhanced to improve decodes.
* Radio reference site editor updated for phase 2 sites to allow user to select FDMA or TDMA control.
* Decode events are now minimized and de-duplicated.
* Fully parsing all phase 1/2 messages from the latest ICD.
* Vendor specific messaging recoveries (Moto & Harris).
* Patch group management enhancements with stale patch detection.
* Tuner editor now fully resets the min/max frequency values
* Default traffic channel count increased to 20 (from 3).
* ISSI roaming radio and talkgroup values now displayed and aliasable as fully qualified values (e.g. 1234(123.456.7890)
* Moto emergency alarm activation messaging support
* Expanded list of P25 encryption algorithms
* Message (bits) viewer enhanced for P25 phase 1 and phase 2
* IPV4 addresses and UDP ports no longer classified as user values - won't display in event views.
* New framework for describing message binary fields that should reduce overall memory footprint and enhance code readability
