Recon raw repeat (#1658)

* UI for Recon Repeater config
* persistent recon repeat settings
* record_view: added possibility to force keep the provided record filename
* working auto record to same file
* Recon TX 
* added Repeater type
* adding yellow coloring on Repeater config+a modal, comments in the code
* default repeater values
