Generated functions.txt separate functions from constants

[Somebodyisnobody]

Constants are shown with a [Function]-stanza in the generated functions.txt. To spearate constants from functions in legacyclonk/LegacyClonk#72 we need to export the constants with a [Constant]-stanza.

Functions are identified by the <func> tag in the corresponding xml:

	<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>

	<funcs>
	<func>
	<title>C4D_All</title>
	<category>Objekte</category><subcat>Kategorie</subcat>

it is an old penalty that constants are documented in <func> tags.
There are <constants> and <constant> tags required.
