`ChangeLog` needed for successful run of `bootstrap`

[paulmenzel]

With commit f9aa9620 running ./bootstrap fails.

$ ./bootstrap 
+ aclocal -I config
+ libtoolize --automake --copy --force
+ autoheader
+ automake --add-missing --copy --force-missing --gnu
configure.ac:37: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated.  For more info, see:
configure.ac:37: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation
configure.ac:43: installing 'config/compile'
Makefile.am: error: required file './ChangeLog' not found
+ exit 1

This looks like a regression introduced by commit e1cdf39d, which removes ChangeLog.

Ah, thanks for catching that. This project has been slightly neglected. We could probably revert e1cdf39d1fd9d97f99c79b923a83870df9d154b1, and update ChangeLog via git commit log -- or we could add --foreign to automake options. Any preferences?
