Fixes FS#2837

Replace tabs with spaces to fixed the
Generic.WhiteSpace.DisallowTabIndent.TabsUsed sniff.

Removed extraneous whitespace to eliminate errors reported by the
Squiz.WhiteSpace.SuperfluousWhitespace sniff.

The old 'default' template was deprecated with the release of the new
'dokuwiki' template (2012-10-13). It is still available in a separate
repository here: https://github.com/dokufreaks/template-default

But no-one in the core development team intends to maintain this template
anymore. So, anyone willing to adopt it is welcome to clone it and make it
your own.
