(svn r3707) -Fix: made the generated Finnish town names sound more Finnish (ln-)
note: <ln-> Bjarni: please go ahead and commit it, i'll take the responsibility if something should go wrong.

(svn r2685) -Codechange: Split the music/sound/video drivers into separate files and move them into subfolders.
This results in shorter and hopefully easier to maintain files.
Note: I had to change paths in #include statements of some unrelated files, because I added the ottd base directory to the include path (-I.)

(svn r1929) Feature: [namegen] Support for dynamic generation of the Czech town names.

The static names are still used in 1/4 of cases. I think the tables for
dynamic generation must look pretty spectacular. :-) New stems are still
needed and there can be occasional glitches, please let me know.

I guess that this method of dynamic generation could be used for at least
Slovak town names, too. And possibly other Slavic languages?

(svn r1926) Codechange: Renamed some of the predefined town names arrays for consistent naming.
- name_spanish_1, name_french_1, name_czech_1, name_romanian_1, name_finnish_1
and name_german_hardcoded were renamed to *_real.
- name_slovakish_1 was renamed to name_slovak_real.
- name_finnish_2[ab] was renamed to name_finnish[12].
- Added comment near the town_names setting definition about the "Slovakish"
pigginess.

(svn r1307) -Fix/feature: rewrote the townname generation code. Code is much more
readable now. 'American' is replaces by 'Additional English' (Jango)
