Bug 737815 - Graphs cannot be generated correctly

Revert x axis renderer from DateAxis to CategoryAxis.
It looks like the DateAxis renderer wasn't meant to be
used for a bar chart.
Redo the highlighter in barcharts.

The formatting code was removed with the introduction

poorly formatted information though which is now fixed again
Some minor cosmetics in the barchart code

Remove bare percent sign in taxinvoice.scm, replace with English.

The bare percent sign in this string messes with po translation
files and causes difficulties compiling without backslashes and
other pain.  Cleans up the English by using real words.

Revert "Remove bare percent sign in taxinvoice.scm, replace with English."

This reverts commit 289bfc2aefdf203881bc3e130cc98aa720e558df.
Fix some warnings found with msgfmt -c in the po files
Fix invocations of guile function 'load-from-path'

The '.scm' extension prevents loading of a precompiled
version of the file from the %load-compiled-path and
will always trigger an autocompilation instead. Omitting
the extension properly allows the function to load a
precompiled version if it exists and is more recent than
the source file. This is only relevant for guile 2 but
works ok for guile 1.8 as well so it's changed unconditionally.
