* test:clean task also deletes .expected.html files
* LinesOfCode encoder can deal with tokens that have no scanner.
  Tests were added for this.
* JSON encoder load rubygems if necessary.
* NEW :loc as an alias for :lines_of_code
* NEW Scanner methods marshal_dump, marshal_load
  FIXED Tokens dumping (failed while trying to dump @scanner)

- 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

General:
- Declared version 0.7.6.
- Moved WordList, CaseIgnoringWordList, Plugin, PluginHost and FileType
  into CodeRay namespace. CodeRay should be "clean" now, except for the
  String#to_unix helper function.
- Fixed a bit of documentation.
- CodeRay binary: Prepare for streaming switch.

Scanners:
- Added code= alias for string=.
- Added streaming? method: Is this Scanner in streaming mode?
- Enhanced error info a bit.
- Ruby scanner:
  - Highlights Regexp heredocs now. They may be added to Ruby 1.9.
  - Speedups with better support for Ruby 1.9.
  - Change in whitespace handling (faster and cleaner now.)
  - Speed up some operator recognition (saving two string comparisons).
- Declared C and Plaintext Scanners as Streamable.

Tokens:
- Changed Text/Block token recognition (#is_a? ::String for Ruby 1.9 support).
- New method: Tokens#text yields the code string.
- text_size fixed.
- Token kind shortcuts (like r for reserved) are now defined in
  token_classes.rb (instead of encoders/html/classes.rb).

Encoders:
- Debug Scanner added.
- Base encoder class adds to @out when encoding (if @out is set).
- A little Tokens scanner speedup.
- Text encoder uses text_token.
- Statistic encoder counts block tokens.
- Smaller changes in XML and HTML encoders.

Styles:
- cYcnus style defines a debug class now.

Duo:
- scanner and encoder are now methods. Scanner and Encoder are created (and
  cached) when needed, not earlier.
- Documented.

Tests:
- Disabled encoder and scanner list check (breaks too often).
- Added identity test, which checks if tokens#text matches the input.
- Added nocolor switch.

Developer tools:
- Benchmark uses Encoder#file_extension for output now.
- Rakefile: Support for 19, 18, yarv and ruby switches for easy comparing
  different Ruby versions.
- Statistic: Demos are no longer tests.
