Title: [scheme] implement complete R5RS number support

The number matching code for Scheme mode now supports the complete numeric grammar as defined by R5RS. This includes exactness modifiers and digit placeholders, additional exponent markers, base modifiers with correct digit constraints, rational notation, and various complex forms.

See the bottom half of R5RS Section 7.1.1 (http://www.schemers.org/Documents/Standards/R5RS/HTML/r5rs-Z-H-10.html#%_sec_7.1.1) for precise definitions.

Unrelated but also present is a small change making #t and #f matches case-insensitive.
