Bug 24899: Reindent record matching rules template

This patch reindents the template the record matching rules template.
The only non-whitespace changes where lines were combined or split.

The diff using the '-w' flag to ignore whitespace should
highlight only moved lines.

Test that functionality is unaffected: Administration -> Record matching
rules.

Test adding, editing, and deleting record matching rules. Test adding,
editing, and deleting match points and match checks. Confirm that
changes are saved correctly.
