changeset 15097:93be1a09c608 draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
(svn r19723) -Add: a simple sprite alignment helper. It does not store the new offsets anywhere so as soon as the sprite is reloaded the offsets are gone (use a bigger sprite cache if this happens). Also anything that reloads NewGRFs (new games, loading games or (re)applying NewGRFs) clears the sprite cache and as such resets the offsets.
