Don't restrict Travis builds to the master branch
Rename Tracking::Config to Tracking::TrackingConfig

Before this change, Ruby 2.0.0 would give "use rbconfig instead of obsolete and
deprecated config" errors. This change fixes the issue.
Manually load Tracking's source files in the right order to prevent load errors
Move the readme badges down a line
Update the code climate badge
Update rdoc and redcarpet
Merge branch 'master' into feature/terminal-table
