added .gitignore based on trunk

git-svn-id: svn+ssh://svn.code.sf.net/p/gramps/code/branches/maintenance/gramps34@22687 4ae1f11a-8b86-4847-b8af-ab372f36d1fd
Added gramps34 stuff deleted later to .gitignore

Various autotools-related junk et al.
"gramps" itself still shows as untracked,
but I don't want to add it as there's also example/gramps
that will get shadowed, too...

6915: not related tool treats siblings as not rel.

Applying patch from ennoborg, thanks!
