Removal of SVN ID line as it is not needed.

[sdcloudt]

SVN is not used anymore. Therefore the /* $Id$ */ lines are not necessary. This PR removes most, if not all, id lines.

I checked the commit, but I would appreciate as checking 1203 files is a job which I nobody wants to do.

I used the following line of bash code to remove all /* $Id$ */ lines:

for file in **/*
do
  sed -Ei '1{N; /^\/\*\s\$Id\$\s\*\/\n$/d}' $file
done

*.sq files are generated, you'll need to change

OpenTTD/src/script/api/squirrel_export.awk

Lines 57 to 58 in f1204f0

	print "/* $I" "d$ */" CR
	print "" CR

and

OpenTTD/src/script/api/squirrel_export.vbs

Lines 86 to 87 in f1204f0

	file.WriteLine "/* $I" & "d$ */"
	file.WriteLine ""

Also remove that merge commit, not sure how it got past the checker...

[glx22]

The checker accepts it because we rebase before the check so it just disappear I think

I screwed up the git, I am fixing it.

I removed some more $Id$ tags, and, removed the generated $Id$ output.
