Qt5 built in qwt (#570)
- qt4->qt5
- in built qt5 6.1.5 because rhel7 is not upto date with qt5, removed findqwt.cmake
- made a fix in qwt lib (qwt_plot_layout.h) to work with 5.15 and lower versions for qrect constr.
- qt5 forms fixed, qt4 many hard coding forms switched to forms including qtabwidget, scrolls etc, fonts moved to forms
 - docking option enabled by default, removed option to disable docking feature from "Mode"
- added qVersionResolve utility functions to handle compatibility before and after qt5.12
- qtplots (ian's code) takes in gain mode enable to set some settings within the class, with proper gain plot ticks
- ensure gain plots have no zooming of z axis in 2d and y axis in 1d
- removed placeholder text in qpalette in main window form as its not supportd until 5.12 (so using qt5.9 designer insted of qt5.15 to cope)
- tab order
Servers:
- fixed some error messages that were empty for fail in funcs (mostly minor as if this error, major issues)

\brief Attributes of an entry on a legend
QwtLegendData is an abstract container ( like QAbstractModel )
to exchange attributes, that are only known between to
the plot item and the legend.
By overloading QwtPlotItem::legendData() any other set of attributes
could be used, that can be handled by a modified ( or completely
different ) implementation of a legend.
\sa QwtLegend, QwtPlotLegendItem
\note The stockchart example implements a legend as a tree
with checkable items
