Accent sidebar on ridelist right height

.. needs to account for font metrics and not just default
   to 50 high. Only notice this if the user has larger fonts
   which can be common on high DPI screens.
Recompute Metrics on W' change

.. and also fix CRC code that stops recompute if the ride file
   hasn't changed since it may be recomputed for other reasons !
Add recent contributors

.. Dr Phil Skiba for TISS etc
.. Michael Puchowicz for the Veloclinic PD Model
.. Jörn Rischmüller for supporting German translation
Extend Theme color coverage

.. to include power, cadence etc

.. this is particularly relevant for colors that need to change
   if we have a light background (e.g. power in yellow on white
   is almost impossible to see for some people)
Added Schoberer Color Scheme

.. mimic colors used by SRMWin and the scheme is named after
   the founder of SRM Ulrich Schoberer
Tweak Alt default to light gray
Add Overlay to AllPlot

.. show interval details when hovering over them on the ride
   plot using the new overlay widget
Be consistent - 'Overlay' not 'Show Overlay'
Refactor CPPlot to use new PDModel

.. the last piece of the jigsaw for the CP chart refactoring was
   to use the new model class and remove the calculation in CPPlot.

.. we have now removed the ridefilecache out of CP, the model calculation
   and refactored to support multiple models.
Mustang theme highlight

.. was invisible, now made more obvious
Notes keyword "Reverse" to set fg color

.. when color is used for background -- since they are independent
   of the plot colors etc in this case.
Merge branch 'master' of github.com:/GoldenCheetah/GoldenCheetah
Fix RideFile::getWeight() Withings bug

.. the update in commit 53871e9 inadvertently broke
   withings weight being used.
CP w/kg fixups

.. all the recent work on the CP chart has focused on absolute
   watts and not taken into account w/kg !

.. this fixes that up, but still need to look at w/kg on the
   model parameters stuff for the CP history chart
Release notes update

.. to reflect recent changes.
Translation Enablement + some small changes

...ConfigDialog.cpp
- -Increase overall size of window (for NON Mac only so far) - this
eases the translation as in non EN languages

- Correction: if Directoy Browsing was Aborted without selection - the
previous value was deleted

Translation Enablement + some small changes
Center the Preferences Icons

.. now the config dialog is a bit wider (to accomodate longer
   texts in other languages, e.g. Deutsche).
Make ConfigDialog bigger on Mac too
Add Model Data to CP export

.. if a model is active we can get the model values now
   using PDModel::y() which is kinda neat !
