data update (mainly updates in Buch and Schwanebeck)
typ2legend.pl: new -debug-parser option
typ file: changed ids of city_limit signs

It seems that the used ids (0x72/0x01 and 0x72/0x03) were not visible
on a real Garmin device). So the ids were changed to 0x74/0x01 and
0x74/0x02.

This is also the first version of the TYP and TXT files produced by
TYPViewer. The previously used online editor at ati.land.cz is not
available anymore.
srt-style change for the previous typ file change

city_limit and locality_name ids changed.
typ2legend: support for TYPViewer output

Changed various parts of typ2legend to work with the decompiled .TXT
files as created by TYPViewer. Support for the .TXT files as created
by ati.land.cz was dropped completely.

Current result is that the legend for M000002a.TXT looks roughly the
same as before.
typ2legend does not have some "hacky" options anymore

Adjusted Makefile.
adjust typ2-legend-xpm.t
Merge branch 'typ-generator-change'
