Qt5 built in qwt (#570)

Browse Source 
- 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)

.SH "Detailed Description"
.PP
A class which draws a legend inside the plot canvas\&.
\fBQwtPlotLegendItem\fP can be used to draw a inside the plot canvas\&. It can be used together with a \fBQwtLegend\fP or instead of it to have more space for the plot canvas\&.
.PP
In opposite to \fBQwtLegend\fP the legend item is not interactive\&. To identify mouse clicks on a legend item an event filter needs to be installed catching mouse events ob the plot canvas\&. The geometries of the legend items are available using \fBlegendGeometries()\fP\&.
.PP
The legend item is aligned to plot canvas according to its \fBalignment()\fP flags\&. It might have a background for the complete legend ( usually semi transparent ) or for each legend item\&.
.PP
\fBNote\fP
.RS 4
An external \fBQwtLegend\fP with a transparent background on top the plot canvas might be another option with a similar effect\&.
