- Move all application related files to subpackage veusz, leaving
only actualy python modules in the python-veusz pkg.
- Hardlink icons from pixmaps/veusz to hicolor-icon-theme, as
symlinked icons lead to appstream-builder being unable to
detect them and vetoes the application consequently.

- Update to version 1.24:
+ Text labels can now include Python expressions inside %{{ }}%
+ Added built-in functions DATE([fmt]), TIME([fmt]), FILENAME()
and BASENAME() when evaluating expressions, which are useful
when used in labels
+ Added Python dictionary ENVIRON when evaluating expressions,
to obtain values from environment variables
+ Added DATA(name, [part]) function to expression environment
for accessing values from datasets, useful for function
evaluation or labels
+ Added SETTING(path) function for expression evaluation to
obtain values of settings
+ Added ESCAPE(text) function to environment, which allows LaTeX
special characters to be displayed in labels
+ Add fractions and percentages units to polar plot
+ Allow number of spokes to be varied in polar plot
+ Widgets can be clicked holding down shift or ctrl, to add or
toggle their selection
+ Add K. Moreland's cool-warm colormap (thanks to S. Richardson)
+ Added further green-map, blue-darkred, blue-darkorange,
brown-blue and blue-orange colormaps from Oregon geography
dept.
+ Add logarithm and exponential dataset plugins
