Fix extra space added in beginning of commit message

Removes extra space in merge commit messages. This seems to have been
introduced by the functionality added in 38d8d749d which allows a user
to change a merge commit message.
Only one link per email to prevent clicking the wrong one.
Added the dump.rdb file to gitignore

Whenever i'm working on GitLab I have redis running, but redis is
generating a db dump file called dump.rdb, I dont think that should be
checked in, so it should be on the gitignore list
Add optional parameter to list merge requests

Add an optional parameter to list merge requests to restrict the
returned merge requests to those that are "opened", "merged" or
"closed". By default all merge requests are returned. Note that
"all" can be given to explicitly request all merge requests.
Update installation.md

just fix typo

fix broken links
No need to edit database.yml for standard Postgres

Postgres running on localhost should recognize the `git` system user
used by GitLab so there is no need to set/change database passwords.
Be more specific about when to edit database.yml
Better title format for wiki page

The title format for wiki page may be unintelligible.
For example 'GitLab' is converted to 'Git Lab', 'MySQL' is converted to
'My Sql', etc.
Add patch release document.
EE changelog note.
