Semi automatic creation of ranges for power zones (#4543)

* Changed the UI of CPPage to inline-editing of all values in all tables
* Added a sports-specific selector for the model (cp2, cp3, ext, manual)
* Allowed to create new ranges either manually or based on the estimated
  values of the model
* Added option to reset each ranges values to those of the selected
  model
* Added message to create a new range if todays estimate differs from
  those of the currently active one
* Refined semi automatic power zones
* Added a dialog to inspect and accept only some values while adoption
* Added info messages
  * when the model does not provide FTP or PMAX
  * that AeTP is only a very rough estimate
* Added a tolerance in comparison before proposing new values
* Using the following order for defaults when adding a new manual range
  * selected row
  * last row
  * predefined defaults
* Zones-Tab: To prevent crashes, a message is shown instead of the real
  interface if a metric refresh is ongoing
* Changed Pace- and HR-Tabs to use inline editing
* Moved the unittests into the same structure as the sourcecode
* Added a simple (incomplete) unittest for kphToPace
* Improved setting the column width
* En-/Disabling the action buttons (add, delete, ...) based on the
  contents state
* Changed the layout to prevent jumping widgets when showing / hiding
  buttons
* Fixed compiler warnings from Visual-C++
* Adopt dialog: Refined layout
