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
\fBQwtDial\fP class provides a rounded range control\&.
\fBQwtDial\fP is intended as base class for dial widgets like speedometers, compass widgets, clocks \&.\&.\&.
.PP
.PP
A dial contains a scale and a needle indicating the current value of the dial\&. Depending on Mode one of them is fixed and the other is rotating\&. If not \fBisReadOnly()\fP the dial can be rotated by dragging the mouse or using keyboard inputs (see \fBQwtAbstractSlider::keyPressEvent()\fP)\&. A dial might be wrapping, what means a rotation below/above one limit continues on the other limit (f\&.e compass)\&. The scale might cover any arc of the dial, its values are related to the \fBorigin()\fP of the dial\&.
.PP
Often dials have to be updated very often according to values from external devices\&. For these high refresh rates \fBQwtDial\fP caches as much as possible\&. For derived classes it might be necessary to clear these caches manually according to attribute changes using \fBinvalidateCache()\fP\&.
