The data structure holding the UI elements in the browser listbox was a
terrible mess - it held the items in an unordered_map, but then accessed
them via a vector containing iterators to this unordered_map.

Fixed the problem (and cleaned all this up) by removing the vector of
iterators, and turning the unordered_map into a normal vector.  When we need
access by name, we just go through all the items; it is always just a handful
of them anyway.

We use pretty old compiler for the official build, so it should be compatible
with most systems. The old system libraries breaked 3rd-party extensions.
There were also problems with exceptions hadnling.

Although fdo#45330 was a duplicate of fdo#45117 which was fixed
earlier, this patch makes the layout look better when the button
text is very long, because it resizes the boundary boxes of fixed
text and ruler, too. I've changed the sequence of
the functions in InitSize() and the size calculations.

This is an inline function, so there should be no problems with binary
compatibility.

Otherwise lines like:

export CLASSPATH=C:/PROGRA~2/Java/JDK16~2.0_2/jre/lib/rt.jar;.

will cause problems on Windows.

"localize" is now directly a C++ program w/o wrapper script.  Also,
its command line has changed slightly, taking the source root as
explicit argument (instead of implicitly as cwd).

otherStyle needs to be used to format tables.
removed wrong defaultStyling.
added using masterslide style info correctly.
