use simplecov with ruby19 and above
are you realy use Gem lower then 1.2?

- maybe no need for this backward compatible
abandon jeweler, because it does not compatible with ruby19
ruby18 compatible test
add travisCI support

- notification by email
- remove Gemfile.lock for multi ruby version support
fix simplecov config problem and add some group
add some rspec config
change some coding style
ruby19 compatible spec change
fix Namespec error
add coveralls
upgrade rspec to 2.11+
code style improve
NEED review: I'm not sure this change is allright
Complete compabilities with ruby18 to ruby20

- Feature: add travis-ci support for cross rubies test
- Feature: add coveralls support for spec coverage calc
- BugFix: fix ErrorCodes namespace problem
- Compatible: custom dependency on different RUBY_VERSION
