Remove placeholder options specs, refs #118.
Allow integer rulers to be turned off at cmd line

Rulers that take an integer option did not accept 'off' or 'false' at
the command line, essentially meaning that they could only be disabled
through config.

Refs #117, #118.
Mark other options that take a NUMBER as integers.
Nested config in recursive_file_sets, refs #116.
Add spaces_after_conditional ruler, refs #91.
Made spec for gh-112 pending
