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)

In Qt >= 5\&.0 QPixmap::fill() is a nop, in Qt 4\&.x it is buggy for backgrounds with gradients\&. Thus \fBfillPixmap()\fP offers an alternative implementation\&.

If we have an integer based paint engine it is also checked if the painter has a transformation matrix, that rotates or scales\&.

.PP
En/Disable line splitting for the raster paint engine\&. In some Qt versions the raster paint engine paints polylines of many points much faster when they are split in smaller chunks: f\&.e all supported Qt versions >= Qt 5\&.0 when drawing an antialiased polyline with a pen width >=2\&.
.PP
Also the raster paint engine has a nasty bug in many versions ( Qt 4\&.8 - \&.\&.\&. ) for short lines ( https://codereview.qt-project.org/#/c/99456 ), that is worked around in this mode\&.
.PP
The default setting is true\&.
.PP
\fBSee also\fP
.RS 4
\fBpolylineSplitting()\fP
.RE
.PP
.SS "void QwtPainter::setRoundingAlignment (bool enable)\fC [static]\fP"
Enable whether coordinates should be rounded, before they are painted to a paint engine that floors to integer values\&. For other paint engines ( PDF, SVG ) this flag has no effect\&. \fBQwtPainter\fP stores this flag only, the rounding itself is done in the painting code ( f\&.e the plot items )\&.

The default setting is true\&.
