Fix spelling mistake in viewlayout

[Kristina Hoeppner]

Using "codespell" (can be installed via Ubuntu's package manager) and running it over the language directory in Mahara 16.04, I found 1 mistake:

./en.utf8/help/forms/viewlayout.createcustomlayouttitle.html:5: arrangment ==> arrangement

Since this is just a typo, no new language string needs to be created, but the issue can be fixed easily by correcting the typo.
