AllPlot Stacked by Series

Extending the stack display to have a single plot for each
data series. This will be useful when comparing activities
and also makes it a bit easier to see the data when there
are lots of data series.

This is a checkpoint commit as I need to fixup some of the
series that have multiple curves and also reference lines
are not currently working.

But you can zoom using the fullplot and highlight intervals
etc.
Remove errant qDebug statements
Update website for 3.0.1 release
Remove ScopeBar from MainWindow

.. moving view selection to center of toolbar.
Move Cocoa release pool to main

.. because mainwindows come and go and we need to persist
   across them all.
Add Fedora 18/19 x86_64 RPMs for downloading
Fixup Stack By Series

Finish off the nits and missing pieces for the recent
update to enable plotting in a stack by data series;

* Now plots W' bal, LR Balance and headwind
* Stacks are now redrawn when settings change
* Interval marking is fixed
* Baseline is now set correctly for each plot
* Reference lines are plotted (on power plots only)
* Reference lines can be dragged
* Interval markers are not redrawn with the text
  only shown on first plot
Fixup Stack View Zooming

.. it was a bit shit with controls you couldn't
   use, and when you did nothing happened.

.. now has a slider and 7 distinct settings for
   stacks from ok to large and 5-60 mins sections.

.. should be good enough for most users.
Zoom to really large

.. because when we're comparing we'll need it.
Fixup Compare Drag-N-Drop

We have two new mime data types;

application/x-gc-intervals
application/x-gc-seasons

With packing routines into QMimeData declared
in IntervalTreeView and SeasonTreeView.

To get around an issue with overwrite mode on
drag and drop from the seasons / interval trees
we DO NOT ACCEPT the drop (even though we do
actually process the data).

All we need to do now is unpack the QMimeData in
ComparePane and then add the GUI elements to it etc.
CPintPlot: Correct AxisScale for IntervalCurve (eg. HeadWind)
Fix compile error on stackZoomWidth

Gareth's build system baulked at the stackZoomWidth
class member defined as const in the class declaration.

Moved to a static member of AllPlotWindow.cpp instead.
RideNavigator no scrollbar on QT5

No need to adjust sizes to account for a scrollbar
on Mac in QT5, since the scrollbars are zero width.
oopsie on #ifdef

.. too Mac centric in last commit, forgot we might need to
   worry about other pesky operating systems.
AllPlot: Handle noTemp with no smooth
fix #634
AerobicDecoupling: Correct formula
fix #721
MainWindow Refactor Part 5 of 5 - TABBED ATHLETES

The final part (and one of the reasons) for the mainwindow
refactoring -- we now support tabbed athletes rather than
having a new mainwindow for each athlete opened.

Context is saved/restored and there are new functions for
opening and closing tabs and windows of tabs.

The tabbar itself is fugly -- the next few days will spend
some time looking at making it prettier on Linux/Win and
more native on Mac (see MMTabBar).
Missing <QStackedWidget> in MainWindow.h

.. needed to build on QT5
Tabbed Athlete Fixups

* showhideToolbar isn't available on a Mac
* used showhideToolbar for Tabbar (typo)
* setDocumentMode for tabbar on Mac (slightly better)
Show/Hide tabbar as needed

.. only needed when we have >1 tabs so lets hide and
   show it automatically.

.. also added a setting for remembering setting but it
   doesn't do anything as we auto hide/show.
