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
\fBQwtPlotBarChart\fP displays a series of a values as bars\&.
Each bar might be customized individually by implementing a \fBspecialSymbol()\fP\&. Otherwise it is rendered using a default symbol\&.
.PP
Depending on its \fBorientation()\fP the bars are displayed horizontally or vertically\&. The bars cover the interval between the \fBbaseline()\fP and the value\&.
.PP
By activating the LegendBarTitles mode each sample will have its own entry on the legend\&.
.PP
The most common use case of a bar chart is to display a list of y coordinates, where the x coordinate is simply the index in the list\&. But for other situations ( f\&.e\&. when values are related to dates ) it is also possible to set x coordinates explicitly\&.
