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
Painter object trying to paint incrementally\&.
Often applications want to display samples while they are collected\&. When there are too many samples complete replots will be expensive to be processed in a collection cycle\&.
.PP
\fBQwtPlotDirectPainter\fP offers an API to paint subsets ( f\&.e all additions points ) without erasing/repainting the plot canvas\&.
.PP
On certain environments it might be important to calculate a proper clip region before painting\&. F\&.e\&. for Qt Embedded only the clipped part of the backing store will be copied to a ( maybe unaccelerated ) frame buffer\&.
.PP
\fBWarning\fP
.RS 4
Incremental painting will only help when no replot is triggered by another operation ( like changing scales ) and nothing needs to be erased\&.

\fB\fIAtomicPainter \fP\fP
Initializing a QPainter is an expensive operation\&. When AtomicPainter is set each call of \fBdrawSeries()\fP opens/closes a temporary QPainter\&. Otherwise \fBQwtPlotDirectPainter\fP tries to use the same QPainter as long as possible\&.
.TP
\fB\fIFullRepaint \fP\fP
When FullRepaint is set the plot canvas is explicitly repainted after the samples have been rendered\&.
.TP
\fB\fICopyBackingStore \fP\fP
When \fBQwtPlotCanvas::BackingStore\fP is enabled the painter has to paint to the backing store and the widget\&. In certain situations/environments it might be faster to paint to the backing store only and then copy the backing store to the canvas\&. This flag can also be useful for settings, where Qt fills the the clip region with the widget background\&.

.SS "void QwtPlotDirectPainter::drawSeries (\fBQwtPlotSeriesItem\fP * seriesItem, int from, int to)"
.PP
Draw a set of points of a seriesItem\&. When observing an measurement while it is running, new points have to be added to an existing seriesItem\&. \fBdrawSeries()\fP can be used to display them avoiding a complete redraw of the canvas\&.
.PP
Setting plot()->canvas()->setAttribute(Qt::WA_PaintOutsidePaintEvent, true); will result in faster painting, if the paint engine of the canvas widget supports this feature\&.
