 I'm working on making the Channel Scanner more maintainable and fixing
 some lingering bugs. This ticket is just to track the progress.

 DONE

  * It is possible to start the scanner before you set the video source in
 input connections pane. [fixed in patch]
  * It is possible to start the scanner from the channel editor, even if no
 scannable sources exist. [fixed in patch].
  * The scan wizard does not prefer the current card and card input if you
 launch it from the input connections pane [fixed in patch].
  * The scan wizard does not prefer the current source if you launch it
 from the channel editor pane [fixed in patch].
  * The scan wizard does not show always you which card and input it will
 use when scanning [fixed in patch].
  * The scan wizard does not handle multiple input cards correctly. [DONE]
  * We should make the Analog scanner work more like the normal channel
 scanners; at the moment it uses a completely different and mostly
 unmaintained class for scanning which does not play well with XMLTV or
 DataDirect channel insertion, does not handle inputs correctly, etc.
 [DONE]

 TODO
  * The scan wizard classes interact in strange ways: functional classes
 access private portions of the UI classes, the ScanWizard fires off events
 just to run functions it could call directly, etc. [partially fixed in
 patch]
  * #2600 Channel scanner stops scanning after finding (C)VCT
    * We need to seperate finding channels and inserting them
    * We should report channels which are in a channels.conf import, but
 were not found by the scanner (and perhaps allow these to be inserted
 anyway).
    * We should report channels which are in the PAT and have a PMT, but do
 not show up in a VCT and allow the user to insert these.
    * We should optionally allow the user to wait for the PAT and PMTs even
 after a VCT has been found.
  * #1866 DVB Scanning - Remaining Issues
    * Tuned Scan does not use the information found in the NIT to find
 other transports to scan, as it did in previous releases.
    * Other????
