configure.ng: don't require GIT tree to detect version string

Change build system to support new and old GNU automake Starting with GNU automake 1.12, the "de-ANSI-fication support" has been removed, which ngIRCd used to enable building itself on very old systems. Now the problem is, that using automake >= 1.12 isn't working because of the now unsupported M4 macros. Therefore the solution that this patch implements is to dynamically generate the automake input files with our own ./autogen.sh script: configure.ng => configure.in Makefile.ng => Makefile.am This is quite an ugly approach, but it works and enables us to: 1. use current automake >= 1.12 for development and "private builds", 2. still build distribution archives using automake 1.11.x that have "de-ANSI-fication support" enabled in the generated Makefile's. And if you are using Makefile's generated with a automake version newer than 1.11.x (without "de-ANSI-fication support"), the ./configure script warns you not to use this generated build system to generate distribution archives. Drawback of this patch: you MUST use our autogen.sh script, you can't call the autoconf/automake commands directly any more; but autoreconf should still work ...
