Lib:

- Encoder: removed a warning
- Encoders::HTML: don't shadow outer variable
- Plugin: move require_plugin into class namespace
- Ruby Scanner:
  - "alias" keyword recognition
  - better regexp/division distinction
  - recognize ~, !, !=, and !~ as method names (partly Ruby 1.9 only)
  - reordered states for speed

Tests:
- updated coderay-suite to use gem instead of require_gem
- general improvements (more colors!, new parameter: new, new syntax lang.test for only and new)
- fixed ruby suite
- adjusted a lot of Ruby tests (alias uses methods now)
- new tests: ruby/operators, ruby/regexp

Samples:
- fixed/updated ('bout time)

Rake tasks:
- updated to use new rubygems API
