Merge branch 'master' of github:SpaceApi/OpenSpaceDirectory
Added a note that an URL change request should be done by an issue instead of a direct edit.

The reason is that OpenSpaceLint is hosted on a shared host where no git is available and
thus no synchronization (github->shared host) is possible.
Removed the markdown attribute.
Reverted the div to highlight the text, it doesn't work.

Github takes the div, removes the class and the inner markdown isn't rendered.

Fixed space_added_updated

When a new hackerspace gets added, the previously entered
hackerspace will be "updated", because a comma gets appended
to the entry.
This patch should show the actually changed hackerspace in
the commit message (instead of the unchanged previously
entered space). It should also work if an existing hackerspace
is changed.

I did not test this!
